Procedure

A solution of (3R) 3-amino-2-oxo-5-phenyl-1-(2,2,2-trifluorethyl)-2,3-dihydro-1H-1,4-benzodiazepine (0.030 g, 0.090 mmol) and 4-nitrophenylchloroformate (0.018 g, 0.090 mmol) in dry tetrahydrofuran (2 mL) was cooled to 0° C. under argon. Triethylamine (0.013 mL, 0.090 mmol) was added and the reaction stirred for 1 h. Solid 3-piperidin4-yl-3,4-dihydropyrido[3,4-d]pyrimidin-2(1H)-one bisTFA salt (0.90 mmol) followed by triethylamine (0.065 mL) were added. The reaction was allowed to come to room temperature and stirred for 1 h. The reaction was quenched with 1N NaOH and concentrated. The crude product was purified by chromatography (silica gel, 0 to 10% methanol in methylene chloride gradient elution), to give the title compound (0.014 g, 27% yield). MS 592.2276 (M+1).
