Procedure:
A stirred solution of [6-chloro-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, 0.53 mmol) in dimethoxyethane (5 mL) was purged with argon for 5 minutes at room temperature. Tetrakis(triphenylphosphine)palladium(0) (0.031 g, 0.027 mmol), crude 1-bromo-4-(2-chlorophenylsulfanyl)-benzene (0.165 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 {6-chloro-4-[4-(2-chloro-phenylsulfanyl)-phenyl]-3-methyl-naphthalen-2-yl}-acetic acid methyl ester (0.051 g, 20%) as a solid.

Procedure:
A solution of 10.0 g (0.0279 mol) of methyl (S)-3-hydroxy-2-(5-methyl-6-oxo-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-3-ylcarbonylamino)-propionate in 500 ml of tetrahydrofuran was treated while gassing with argon with 7.25 g (0.0304 mol) of methoxycarbonylsulphamoyl-triethylammonium hydroxide internal salt (Burgess reagent) according to the method described in Tetr. Letters 1992, 33, 907. The mixture was boiled at reflux for 1 hr. and completely freed from the solvents. The residue was dissolved in dichloromethane and chromatographed over silica gel with ethyl acetate/ethanol 9:1 as the eluent. There were obtained 4.4 g (46%) of methyl (S)-2-(5-methyl-6-oxo-5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepin-3-yl)-4,5-dihydro-oxazole-4-carboxylate as a white solid. An analytical sample was recrystallized from ethanol/diethyl ether and gave white crystals; m.p. 190-192°. [α]D20 =+45.4° (CHCl3, c=1%).

Procedure:
2.0 g of 2-amino-1-propanol was added dropwise to a stirred mixture of 1.3 g of 60% sodium hydride and 30 ml of N,N-dimethylformamide at room temperature. After the reaction mixture was stirred for 30 minutes, a solution containing 3.7 g of 2-chloropyrimidine dissolved in N,N-dimethylformamide was added dropwise to the reaction mixture. The mixture was stirred for 2 hours at 100° C. After completion of the reaction, the reaction mixture was cooled. The solids in the reaction mixture were filtered off. The solvent in the filtrate was removed under reduced pressure. The residue was purified by column chromatography on silica gel to obtain 2.1 g of the desired product (yield: 50%).
