Procedure:
4-Chloro-2-ethyl-1-{[3-(4-fluorophenyl)isoxazol-5-yl]methyl}-1H-imidazo[4,5-c]quinoline (2.624 g, 6.451 mmol), 7 N ammonia in methanol (40 mL), and tetrakis(triphenylphosphine)palladium(0) were combined in a pressure vessel and heated at 120° C. for 16 hours. An analysis by HPLC indicated that the reaction was incomplete. The volatiles were removed under reduced pressure, and the residue was dissolved in chloroform. The solution was washed sequentially with aqueous potassium carbonate, water, and brine; dried over magnesium sulfate; filtered; and concentrated under reduced pressure. The resulting dark yellow solid was added to a pressure vessel with 7 N ammonia in methanol (60 mL), and the reaction was sealed and heated at 150° C. for 18 hours. The volatiles were removed under reduced pressure, and the residue was stirred with 0.5 N potassium hydroxide in methanol for 30 minutes. The resulting solid was isolated by filtration, diluted with dichloromethane, purified by column chromatography on silica gel (eluting with 5% to 10% CMA in chloroform), triturated with diethyl ether and filtered, and recrystallized from acetonitrile after a hot filtration. The crystals were isolated by filtration, washed with diethyl ether, and dried to provide 0.139 g of 2-ethyl-1-{[3-(4-fluorophenyl)isoxazol-5-yl]methyl}-1H-imidazo[4,5-c]quinolin-4-amine as a white powder, mp 232.0-233.0° C.

Procedure:
8.5 g of thionyl chloride are added dropwise over a 10 minutes span to a stirring mixture of 13.0 g of 2-(4-fluorophenoxy)benzyl alcohol in 80 ml of benzene at ambient temperature. After total addition, the reaction mixture is stirred for 16 hours before being carefully poured onto 350 ml of crushed ice containing 8 ml of sodium bicarbonate. The mixture is stirred until the ice melts. The layers separate and the benzene layer is successively washed twice with 40 ml portions of a half saturated sodium bicarbonate solution, washed twice with 40 ml portions of water, washed once with a 25 ml portion of a saturated sodium chloride solution, dried and rotary evaporated to provide a clear liquid. The liquid is distilled at 106°-109° C. and 0.16 mm to provide a clear colorless liquid of 2-(4-fluorophenoxy)benzyl chloride.

Procedure:
A solution of 4-nitrophenyl chloroformate (188 mg, 0.931 mmol, 1.10 equiv) in dichloromethane (5 mL) was added dropewise to a solution of (1S)-1-cyclopropyl-2-[(2S)-4-(2,5-difluorophenyl)-2-phenyl-2,5-dihydro-1H-pyrrol-1-yl]-2-oxoethanamine (16-7, 300 mg, 0.847 mmol, 1 equiv) and triethylamine (0.354 mL, 2.54 mmol, 3.00 equiv) in dichloromethane (10 mL) at 0° C.

Procedure:
A solution of 1.75 g of 1,4,7,10-tetraazacyclododecane and 1.63 g of hexamethylphosphorous triamide in 50 ml of toluene is refluxed for 12 hours. Titration of the off-gases with 1 N HCl indicates that 97% of the theoretical amount of dimethylamine is evolved in this time. The toluene is removed under reduced pressure to give 2.0 g of 1,4,7,10-tetraaza-13-phosphatricyclo[5.5.1.04,13 ]tridecane as a white solid which melts at 109°-111° C with sintering from 90° C (possibly because of the presence of a trace of toluene). Sublimation of this product at 75° C and 0.55 mm gives large colorless crystals, which melt at 111°-113° C. The mass spectrum shows an M+ ion at 200; measured mass, 200.1194; calc'd, 200.1190.
