Procedure

2-(S)-(4-Fluoro-phenyl)-N-(1-(S)-formyl-2-methyl-propyl)-4-morpholin-4-yl-4-oxo-butyramide (350 mg, 0.96 mmol, 1.0 eq.) and 5-Amino-2-methoxy-pyridine (240 μL, 1.92 mmol, 2.0 eq.) dissolved in MeOH (2.5 mL) and acetic acid (106 mL, 1.92 mmol, 2.0 eq.) added via syringe at room temperature. Sodium cyanoborohydride (121 mg, 1.92 mmol, 2.0 eq.) added in portion and the reaction monitored the reaction by LC/MS. Upon completion, solvents were evaporated and dissolved in EtOAc (100 mL) washed with brine, dried over MgSO4, filtered and evaporated. Purification by preparative mass-directed HPLC provided the title compound as a white solid after evaporation and lyophilization (2.6 mg, 5.6 □mol, 0.6%). HPLC-MS calcd. for C25H33FN4O4 (M+H+) 473.3, found 473.5.
