Procedure

To a rt solution of tert-butyl(3S,4S)-7-cyano-1-((3-cyclopropylquinolin-4-yl)methyl)-4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylcarbamate (93 mg, 187 μmol) in pyridine (374 μl) was added tetrahydro-2H-pyran-4-carbonyl chloride (139 mg, 935 μmol) dropwise. The reaction was stirred at 80° C. for 2 h, then cooled to rt, diluted with EtOAc, washed with H2O, sat. aq. NaHCO3, and sat. aq. NaCl, dried over Na2SO4, filtered, and concentrated. The crude material was purified by flash chromatography to provide tert-butyl(3S,4S)-7-cyano-1-((3-cyclopropylquinolin-4-yl)methyl)-4-methyl-2-oxo-5-(tetrahydro-2H-pyran-4-carbonyl)-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylcarbamate (69 mg, 61%) as an off-white solid. MS m/z 610 (MH)+.
