Reaction Steps

A solution of 4-[[4-[(5-amino-2-phenoxy-pyridin-4-ylmethyl)-amino]-4-(S)-(tetrahydro-pyran-4-yl)-butyryl]-(2-benzyloxy-ethyl)-amino]-cis-cyclohexanecarboxylic acid benzyl ester (0.5 g, 0.7 mmol) and BrCN (3M in CH2Cl2, 0.25 mL) in EtOH (20 mL) was stirred at room temperature overnight. The EtOH was evaporated. The resulting oil was stirred in diethyl ether (50 mL) for 30 min. 4-[[4-(2-Amino-6-phenoxy-4H-pyrido[3,4-d]pyrimidin-3-yl)-4-(S)-(tetrahydro-pyran-4-yl)-butyryl]-(2-benzyloxy-ethyl)-amino]-cis-cyclohexanecarboxylic acid benzyl ester was collected as a solid as its corresponding HBr salt.
