Procedure:
A stirred solution of [6-fluoro-3-methyl-4-(4,4,5,5-tetra methyl-[1,3,2]-dioxaborolan-2-yl)-naphthalen-2-yl]-acetic acid methyl ester (0.2 g, 0.55 mmol) in dimethoxyethane (5 mL) was purged with argon for 5 minutes at room temperature. Tetrakis(triphenylphosphine)palladium(0) (0.032 g, 0.028 mmol), impure 1-bromo-4-(4-chlorophenylsulfanyl)-benzene (0.25 g) and 1.0 M aqueous sodium bicarbonate (5 mL, 5 mmol) were added simultaneously to the reaction mixture under argon. The reaction mixture was refluxed for 2 hours and then brought to room temperature. Water was added and the resulting mixture was extracted twice with ethyl acetate. The combined organic extracts were washed with water and brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to give the crude product, which was finally purified using flash chromatography (0-3% ethyl acetate in hexanes) to give {4-[4-(4-chloro-phenylsulfanyl)-phenyl]-6-fluoro-3-methyl-naphthalen-2-yl}-acetic acid methyl ester (0.094 g, 37%) as a solid.

Procedure:
To the trans-2-tridecenal (1.7 g) dissolved in methylene chloride (80 ml) was added (carbomethoxymethylene)triphenyl phosphorane (4.0 g), and the mixture was stirred for 2 hours. The reaction mixture was subjected to chromatography on a silica gel column with eluent systems of n-hexane-ethyl acetate (from 100:1 to 20:1) to give the methyl ester of trans,trans-2,4-pentadecadienoic acid (2.1 g). Potassium hydroxide (2.0 g) was dissolved in a mixed solvent of ethanol-water (1:1), and the methyl ester of trans,trans-2,4-pentadecadienoic acid (2.1 g). After the mixture was stirred at 60° C. for 40 minutes, it was cooled, adjusted to a weak acidic range of pH with citric acid and extracted with ethyl acetate. The ethyl acetate layer was dried over anhydrous sodium sulfate and concentrated to give trans, trans-2,4-pentadecadienoic acid (1.9 g). The product was dissolved in N,N-dimethylformamide (DMF, 50 ml ), and para-nitrophenol (1.2 g) and N,N'-dicyclohexylcarbodiimide (1.7 g) were added. The mixture was stirred for 12 hours. After the reaction, precipitates produced were removed by filtration, DMF was removed by distillation, and the residue was subjected to chromatography on a silica gel column with eluent systems of n-hexane-ethyl acetate (from 200:1 to 50:1) to give the active ester of trans,trans-2,4-pentadecadienoic acid (1.3 g). To the active ester (600 mg) dissolved in DMF (30 ml) were added 6-(4'-N-glycyl-spicaminyl-amino)purine hydrochloride (750 mg) and triethylamine (1.2 ml). The mixture was stirred for 12 hours. After the solvent was removed by distillation, the residue was subjected to chromatography on a silica gel column with eluent systems of chloroform-methanol (from 7:1 to 5:1) to give SPK285 in the yield of 530 mg.

Procedure:
To (2′-formyl-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl)-acetic acid ethyl ester (1.0 g, 2.73 mmol) in MeOH (8 mL) was added ethylamine (2M in THF; 5 mL, 10 mmol), followed by acetic acid (0.23 mL, 4.09 mmol). Sodium cyanoborohydride (0.260 g, 4.14 mmol) was then added, and the reaction was stirred at room temperature and monitored by analytical LCMS. The reaction never reached completion, so the mixture was concentrated and partitioned between EtOAc and saturated aqueous NaHCO3. The aqueous layer was extracted with EtOAc, and the combined organic layers were dried over MgSO4, filtered, and concentrated. The residue was purified by silica gel chromatography (0-6% MeOH in CH2Cl2) to give (2′-ethylaminomethyl-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl)-acetic acid ethyl ester.

Procedure:
1,8-Diazabicycloundec-7-ene (DBU) [6674-22-2] (0.4 mL, 2.5 mmol) was added to an ambient temperature, stirred, turbid solution of 3-thiophen-2-yl-4H-pyrazolo[1,5-a]pyrimidin-5-one (354.3 mg, 1.6 mmol), (2-amino-ethyl)-methyl-carbamic acid tert-butyl ester [121492-06-6] (852.2 mg, 4.9 mmol), and (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP) [56602-33-6] (937.7 mg, 2.1 mmol) in acetonitrile (16 mL). Upon addition of the DBU the turbidity clears and the solution was permitted to stir for 2 d then partitioned between brine and ethyl acetate. The extract was dried (MgSO4) and flash chromatographed (silica gel, eluted with 10% (v/v) methanol/ethyl acetate). Evaporation of product fractions yielded an oil which was crystallized from heptane to provide methyl-[2-(3-thiophen-2-yl-pyrazolo[1,5-a]pyrimidin-5-ylamino)-ethyl]-carbamic acid tert-butyl ester as 333.6 mg of yellow, fine crystalline powder, mp. 140-141° C. 1H NMR (400 MHz, DMSO-d6) δ ppm (rotomers present) 1.16-1.28 (m, 5 H) 1.37 (br. s., 3 H) 2.51 (s, 1 H) 2.85 (br. s., 3 H) 3.47 (br. s., 1 H) 3.55 (br. s., 3 H) 6.28 (d, J=6.82 Hz, 1 H) 7.04 (dd, J=5.05, 3.54 Hz, 1 H) 7.30 (dd, J=5.05, 1.01 Hz, 1 H) 7.41 (br. s., 1 H) 7.80 (br. s., 1 H) 8.19 (s, 1 H) 8.48 (d, J=7.07 Hz, 1H). 13C NMR (100 MHz, DMSO-d6) δ ppm 27.81, 27.96, 33.75, 38.41, 46.32, 78.13, 100.28, 100.76, 120.16, 121.75, 126.90, 135.01, 135.20, 140.78, 143.74, 154.91, 155.81.

Procedure:
Ethylchloroformate (0.30 ml, 3.08 mmol) was added to a stirred solution of the amidoxime of Example 8 (500 mg, 1.39 mmol) in pyridine (8 ml) at 0° C. under nitrogen and the resulting solution was stirred for 10 minutes. The mixture was concentrated under reduced pressure and the residue was dissolved in a mixture of water (4 ml), tetrahydrofuran (4 ml) and 1M aqueous sodium hydroxide solution (2 ml). The mixture was heated under reflux for 1 hour, cooled to room temperature and stirred for a further 2 days. The resulting solution was diluted with 2M aqueous hydrochloric acid (20 ml) and extracted with ethyl acetate (2×50 ml). The combined organic layers were washed with brine (50 ml), dried over magnesium sulphate, filtered and evaporated under reduced pressure to leave a yellow oil. The oil was purified by flash column chromatography on silica gel eluting with pentane:ethyl acetate (50:50, by volume) to yield a white solid. The solid was dissolved in a mixture of tetrahydrofuran (1 ml) and 1M aqueous sodium hydroxide solution (10 ml) and then heated under reflux for 24 hours. The resulting solution was diluted with 2M hydrochloric acid (20 ml) and extracted with dichloromethane (2×50 ml). The combined organic layers were washed with brine (50 ml), dried over magnesium sulphate, filtered and evaporated under reduced pressure to give the title compound (113 mg) as a white solid m.p. 94–96° C.

Procedure:
A mixture of the crude 7-benzyloxy-4-chloro-6-methoxyquinazoline, potassium carbonate (50 g, 362 mmol) and 4-chloro-2-fluorophenol (8.8 ml, 83 mmol) in DMF (500 ml) was stirred at 100° C. for 5 hours then allowed to cool to ambient temperature overnight. The reaction mixture was poured into water (21) and was stirred at ambient temperature for a few minutes. The crude solid was collected by filtration washing with water. The resultant solid was dissolved in dichloromethane and filtered through diatomaceous earth. The filtrate was treated with decolourising charcoal, boiled for a few minutes then filtered through diatomaceous earth. The filtrate was filtered through phase separating paper and then evaporated under vacuum to give a solid residue which was triturated with ether, filtered and dried to give 7-benzyloxy-4-(4-chloro-2-fluorophenoxy)-6-methoxyquinazoline (23.2 g, 76%).
