Reaction Steps

To a solution of (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-oxo-5-(piperazin-1-yl)pentyl isoquinolin-3-ylcarbamate (610 mg, 1.07 mmol) in acetone (1 mL) and DCM (1 mL) was added acetic acid (4 drops, ˜0.2 mL). The reaction mixture was stirred at RT for 30 min. To this mixture was added solid NaBH(OAc)3 and the resulting mixture was stirred at RT for 1 h and concentrated. The residue was purified on RP-HPLC using a mixture of acetonitrle and water (0.1% HCOOH buffer). The fractions was collected, concentrated to dryness, and re-dissolved in EtOAc. The organic mixture was washed with Na2CO3, dried over Na2SO4, filtered, and concentrated to give (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-(4-isopropylpiperazin-1-yl)-5-oxopentyl isoquinolin-3-ylcarbamate (540 mg, 82%) as white solid. LRMS (M+H+) m/z 613.3.
