Procedure:
Using the general procedure for Intermediate 1, (4-nitro-benzyl)-urea [J. Med. Chem. 1996, 39, 1924] is converted into 6-amino-3-methyl-1-(4-nitro-benzyl)-1H-pyrimidine-2,4-dione, [MH]+ 277. A solution of calcium chloride (4.94 g, 45 mmol) in water (100 ml) is added to a solution of 6-amino-3-methyl-1-(4-nitro-benzyl)-1H-pyrimidine-2,4-dione (19.08 g, 69.0 mmol) in acetic acid (300 ml). Zinc dust (58.8 g, 900 mmol) is then added portionwise with external cooling. The reaction is stirred at room temperature for 1.5 hours, filtered through a celite plug and washed successively with ethanol and acetic acid. Evaporation of the combined filtrate and washings affords 6-amino-1-(4-amino-benzyl)-3-methyl-1H-pyrimidine-2,4-dione acetic acid salt, [M-3H]− 243. Acetic anhydride (7.2 ml, 76.0 mmol) is added to a cooled (0° C.) suspension of 6-amino-1-(4-amino-benzyl)-3-methyl-1H-pyrimidine -2,4-dione acetic acid salt (17.0 g, 69.0 mmol) in pyridine (260 ml). The reaction mixture is warmed to room temperature, stirred for 6 hours and the solvent evaporated. The residue is triturated with water and the solid collected by filtration and dried to afford N-[4-(6-amino-3-methyl-2,4-dioxo-3,4-dihydro-2H-pyrimidin-1-ylmethyl)-phenyl]-acetamide, [MH]+ 289. Using the general procedure for Intermediate 1, this compound is converted into N-[4-(5,6-diamino-3-methyl-2,4-dioxo-3,4-dihydro-2H-pyrimidin-1-ylmethyl)-phenyl]-acetamide, [MH]+ 304.

Procedure:
Hydroxylamine hydrochloride (2.88 g, 41.5 mmol) was dissolved in methanol (20 mL) and cooled to 0° C. in an ice-bath. Sodium methoxide (2.24 g, 41.5 mmol) was added and the resulting suspension stirred at room temperature for 15 minutes. The suspension was cooled to 0° C., 4,4,4-trifluoro-3-methoxybut-2-enenitrile (26 mmol) was added dropwise and the mixture allowed to slowly warm to room temperature. The mixture was then heated to 60° C. overnight. The white solid was removed by filtration, washed with dichloromethane and the filtrate concentrated under reduced pressure to afford 4,4,4-trifluoro-N′-hydroxy-3-methoxybut-2-enimidamide as a solid, which was used directly in the next step without further purification. The solid was taken in ethanol (25 mL) and the solution acidified (pH=1) with 37% aqueous hydrochloric acid. The resulting mixture was heated to 60° C. for 2 h. Ethanol was removed under reduced pressure and the residue diluted with dichloromethane. A saturated solution of sodium bicarbonate was added (pH=14) and the organic phase separated. The aqueous phase was back extracted three times with dichloromethane, the organics combined, dried (MgSO4) and concentrated under reduced pressure. The resulting crude material was purified by silica gel chromatography (dichloromethane/ethyl acetate 95:5) to isolate 3-(trifluoromethyl)isoxazol-5-amine (446 mg, 11%) along with 5-(trifluoromethyl)isoxazol-3-amine as a minor product. 1H NMR (300 MHz, CDCl3) d 5.31 (s, 1H), 5.03 (bs, 2H).

Procedure:
In a dry argon-purged round bottom flask anhydrous AlCl3 (26.9 g, 0.202 mol) was suspended in anhydrous 1,2-dichloroethane (60 mL). 4-Fluorenecarboxylic acid (10.0 g, 0.048 mol) was added to the suspension. The reaction flask was placed in a room temperature bath and succinic anhydride (5.72 g, 0.057 mol) was carefully added. The reaction was stirred for five hours and then cooled to 0° C. The reaction was very carefully quenched by the slow portion-wise addition of 3 M HCl (Caution! The reaction can react violently when HCl is added too rapidly.) The final well mixed suspension was acidic and not reactive to additional HCl solution. The organic solvent was removed at reduced pressure and the product was filtered and washed well with water. The crude product was dissolved in warm NaOH solution approximately ≦1M NaOH), filtered and precipitated with the addition of concentrated HCl. The product was filtered washed with water and then dried at reduced pressure in the presence of P2O5.

A flask equipped with a stirrer, reflux condenser, dropping funnel and thermometer was charged with 26.2 g (0.1 mol) of N-t-butyldimethylsilyl-N-benzyl-N-allylamine and 0.07 g of a toluene solution of platinum/1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex (Pt concentration 3 wt %) and heated at 50° C. Once the internal temperature became steady, 13.4 g (0.1 mol) of methyldiethoxysilane was added dropwise over 1 hour. Stirring was continued at the temperature for a further 1 hour. The reaction solution was distilled, collecting 31.0 g of a fraction having a boiling point of 169-170° C./0.4 kPa.

NaOH (78 μL, 0.078 mmol) was stirred at room temperature for 20 min. The organic solvents were removed under vacuum and dried to give the crude intermediate, which was dissolved in DCM (0.1 mL), followed by the addition of TFA (0.12 mL, 1.6 mmol). The reaction mixture was stirred at room temperature for 20 min. The solution was then concentrated under reduced pressure and the residue was diluted with MeOH, filtered and purified by preparative LC-MS (XBridge™ preparative C18 5 μm OBD™ column, 30×10 mm, 60 mL/min., eluting with a gradient of MeCN and water with 0.1% NH4OH) to give both diastereoisomers of the title compound as white powders. On analytical HPLC (Waters SunFire™ C18, 2.1×50 mm, 5 μm; flow rate 3 mL/min.; injection volume 2 μL; gradient from 2 to 80% B in 3 minutes (A=water with 0.025% TFA, B=MeCN)) the diastereoisomers had the following properties:

Procedure:
Methyl 6-bromo-2-naphthoate (5 g, 18.9 mmol) was dissolved in purified THF (100 mL) under a nitrogen atmosphere, the reaction solution was cooled down to 0° C., and then diisobutyl aluminum hydride (18.9 mL, 1.0M hexane solution) was added thereto. The reaction mixture solution was stirred at room temperature for 3 hours. Sodium bicarbonate (20 mL) was added to the reaction mixture solution, and then the solvent was removed by extraction with water and dichloromethane. The extracted material was dried in vacuum to thereby obtain a white solid (4.3 g, yield: 95%).

Procedure:
2-[4-({[2-(Benzo[1,3]dioxol-5-yloxy)-pyridine-3-carbonyl]-amino}-methyl)-phenyl]-2-methyl-propionic acid methyl ester (0.451 g) was suspended in tertiary butanol (30 mL). Sodium hydroxide (1.68 mL of a 6N aqueous solution) was added to the suspension, and the reaction mixture was heated to reflux. After 1 hour the reaction mixture was cooled to ambient temperature, the solvent removed in vacuo, water added (20 mL), and the pH adjusted from to 3 with concentrated hydrochloric acid. The solution was subsequently extracted with ethyl acetate (7×50 mL). The combined organics were dried over magnesium sulfate, filtered, and concentrated in vacuo to yield the crude product (0.490 g). The crude product was purified by silica gel chromatography (acetic acid:methanol:dichloromethane=1:10:89) to yield pure title compound (0.409 g).

Procedure:
To the solution of product from step A is added 2 g. of dinitrogen tetraoxide dissolved in dichloromethane, and the mixture is stirred for about 16 hours. Evaporation provides a residue which is mixed with ice and 10 percent sodium hydroxide solution. The mixture is stirred for 15 minutes, then cold 6N hydrochloric acid and diethyl ether are added. The ether layer is separated, then washed with saturated sodium chloride solution and dried. The solution is chromatographed on silica gel, eluting first with carbon tetrachloride, then dichloromethane. The later fractions are evaporated to provide 1-(2-nitro-3-phenyl-5-benzofuranyl)undecan-1-ol as a yellow solid, m.p. 84°-85° C. after recrystallization from hexane.
