The acid addition salts are prepared in a conventional manner by treating a solution or suspension of the free base of formula i or IA with one chemical equivalent of a pharmaceutically acceptable acid. Conventional concentration or crystallization techniques are employed in isolating the salts. Illustrative of suitable acids are acetic, lactic, succinic, maleic, tartaric, citric, gluconic, ascorbic, benzoic, cinnamic, fumaric, sulfuric, phosphoric, hydrochloric, hydrobromic, hydroiodic, sulfamic, sulfonic acids such as methanesulfonic, benzene sulfonic, p-toluenesulfonic, and related acids. The novel compounds of the invention of formula I or IA may be administered alone or in combination with pharmaceutically acceptable carriers, in either single or multiple doses. Suitable pharmaceutical carriers include inert solid diluents or fillers, sterile aqueous solution and various organic solvents. The pharmaceutical compositions formed by combining the novel compounds of formula I or IA and the pharmaceutically acceptable carriers are then readily administered in a variety of dosage forms such as tablets, powders, lozenges, syrups, injectable solutions and the like. These pharmaceutical compositions can, if desired, contain additional ingredients such as flavorings, binders, excipients and the like. Thus, for purposes of oral administration, tablets containing various excipients such as sodium citrate, calcium carbonate and calcium phosphate may be employed along with various disintegrants such as starch, alginic acid and certain complex silicates, together with binding agents such as polyvinylpyrrolidone, sucrose, gelatin and acacia. Additionally, lubricating agents such as magnesium stearate, sodium lauryl sulfate and talc are often useful for tabletting purposes. Solid compositions of a similar type may also be employed as fillers in soft and hard filled gelatin capsules. Preferred materials for this include lactose or milk sugar and high molecular weight polyethylene glycols. When aqueous suspensions or elixirs are desired for oral administration, the essential active ingredient therein may be combined with various sweetening or flavoring agents, coloring matter or dyes and, if desired, emulsifying or suspending agents, together with diluents such as water, ethanol, propylene glycol, glycerin and combinations thereof. For parenteral administration, solutions of the novel compound of formula I in sesame or peanut oil, aqueous propylene glycol, or in sterile aqueous solution may be employed. Such aqueous solutions should be suitably buffered if necessary and the liquid diluent first rendered isotonic with sufficient saline or glucose. These particular aqueous solutions are especially suitable for intravenous, intramuscular, subcutaneous and intraperitoneal administration. The sterile aqueous media employed are all readily available by standard techniques known to those skilled in the art. Additionally, it is possible to administer the compounds of the present invention topically when treating inflammatory conditions of the skin and this may be done by way of creams, jellies, gels, pastes, and ointments, in accordance with standard pharmaceutical practice. The effective dosage for the compound of formula I or IA depends on the intended route of administration and other factors such as age and weight of the patient, as generally known to a physician. The dosage also depends on the illness to be treated. The daily dosage will generally range from about 0.1 to 50 mg/kg of the body weight of the patient to be treated. For the treatment of inflammatory diseases about 0.1 to about 100 mg/kg will be needed in general, for gastrointestinal diseases about 0.1 to about 50 mg/kg, as well as for anorexia nervosa, hemorrhagic stress, treatment of drug and alcohol withdrawal symptoms and treatment of fertility problems. The daily dosage may be given in a single dose or up to three divided doses. The methods for testing the compounds of formula I or IA for their CRF antagonist activity are as described in Endocrinology, 116, 1653-1659 (1985) and Peptides 10, 179-188 (1989) which determine the binding activity of a test compound to a CRF receptor. The binding activity for the compounds of formula I generally ranges from about 0.2 nanomolar to about 10 micromolar. The following Examples illustrate the invention. The designation Et means ethyl.

The reaction mixture was then vigorously refluxed for 2 hours. At 5°C, the reaction was quenched by cautious addition of 15% aqueous sodium hydroxide. The mixture was filtered, and the filtrate was concentrated in vacuo to a yellow solid. The entire sample was then dissolved in methylene chloride (400 ml) and filtered to remove residual inorganic salts. Solvent removal in vacuo afforded the title .compound as an orange solid (47.01 g, 70% yield). TLC R, (silica gel plates, u.v. detection, methanol/methylenechloride=5:95 in volume): 0.46; 13 C NMR(CDCI 3 ): 135.4, 134.1 , 129.3, 126.3, 126.1 , 125.9, 65.4, 55.0, 47.8, 30.9. Preparation 2 Dextrorotatorvenantiomerof ,1 ,2,3,4-Tetrahvdro-isoquinolin-3-yl)-methanol(also referred to as (+)-3-hvdroxymethyl-1 ,2,3,4-tetrahvdroisoquinoline) To asolution of ( ± )-3-hydroxymethyl-1 ,2,3,4-tetrahydroisoquinoline (Preparation 1 ; 47.01 g, 0.288 mol) in isopropyl alcohol (159 ml), a solution of (S)-(+)-mandelic acid -(43.81 g, 0.288 mol) in isopropyl alcohol (159 ml) was added. The resulting solution was allowed to stand at ambient temperature for 48 hours, during which time a heavy orange crystalline mass formed. The isolated crystalline solid (13.06 g) was dissolved in hot isopropyl alcohol (63 ml). After standing for 1 hour at ambient temperature, the newly-formed crystalline solid was isolated by filtration (8.2 g, m.p. 138°C). The recrystallization procedure was repeated twice more, using 63 ml and 60 ml volumes of isopropyl alcohol to afford 7.08 g and 6.76 g of crystalline material, respectively. (In each case, the crystallization was allowed to proceed for 2 hours at ambient temperature prior to filtration.) A 138-139°C m.p. was observed after the final crystallization. The entire sample was dissolved in methylene chloride water (300 ml and 100 ml, respectively) with the pH adjusted to 9.5 (potassium carbonate). The phases were separated, and the aqueous portion was extracted with three 50 ml portions of fresh methylene chloride. The combined organic extracts were dried (anhydrous sodium sulfate) and concentrated in vacuo to afford the optically resolved title compound as a colorless amorphous solid (2.02 g, 8.6% yield). [a] 20 D + 103° (c=1.83, CH 2 CI 2 ); 13 C NMR (CDCI 3 ): identical to that of the racemic compound prepared in Preparation 1.

[a] 20 d -100.4° (CH 2 CI 2 , c=1.43; 'H NMR and 13 C NMR (CDCI 3 ): identical in all respects to those observed for the racemic (Preparation 1) and dextrorotatory (Preparation 2) products. Preparation 4 Methyl 3.5-diethyl-1-(2.4,6-trichlorophenyl)pyrazole-4-carboxylate A mixture of 11.0 g (60.0 mmol) of methyl 2-propionyl-3-ketopentanoate and 11.26 g (65.0 mmol) of 2,4,6-trichlorophenylhydrazine in 50 mL of ethanol was refluxed under nitrogen until disappearance of starting material was noted. The solvent was removed in vacuo and the residues were partitioned between ethyl acetate and dilute hydrogen chloride. The organic layer was dried and evaporated to give the product as an off-white solid which was used for subsequent reactions without further purification. 1 H-NMR: (CDCI 3 ) δ 1.02 (3H, t, J=7), 1.21 (3H, t, J=7), 2.62 (2H, q, J=7), 2.86 (2H, q, J=7), 3.82 (3H, s), 7.42 (2H, s).
