Reaction Steps

A solution of 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]-cyclohexanecarboxylic acid benzyl ester (0.4 g, 0.42 mmol) and Pd (10% on carbon, 0.2 g) in EtOH (50 mL) was subjected to hydrogenation under 10 psi for 48 h. HPLC purification yielded 4-[[4-(2-Amino-6-phenoxy-4H-pyrido[3,4-d]pyrimidin-3-yl)-4-(S-(tetrahydro-pyran-4-yl)-butyryl]-(2-hydroxy-ethyl)-amino]-cyclohexanecarboxylic acid as a white solid and 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 as a white solid.
