Procedure

A rt solution of tert-butyl(S)-1-((3S,4S)-5-acetyl-1-(5-bromo-2-methoxybenzyl)-7-cyano-4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (35.5 mg, 55.2 μmol) in 4 M HCl in dioxane (276 μl) was stirred for 1 h. The reaction was diluted with Et2O and the solids were collected by vacuum filtration, taken up in MeCN—H2O, and lyophilized to provide (S)-N-((3S,4S)-5-acetyl-1-(5-bromo-2-methoxybenzyl)-7-cyano-4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-yl)-2-(methylamino)propanamide hydrochloride (23.0 mg, 72%) as a white solid. MS m/z 542/544 (MH)+.
