To a mixture of (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4-oxo-4-(pyrazin-2-ylmethylamino)butyl isoquinolin-3-ylcarbamate (650 mg, 1.12 mmol) and DCM (50 mL) were added phosphoryl chloride (0.514 mL, 0.00561 mol). The resulting mixture was stirred at RT for overnight. The resulting solution was concentrated. The resulting residue was purified on prep-HPLC (ACN/H2O with 0.1% HCOOH) to give (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-3-(imidazo[1,5-a]pyrazin-3-yl)propyl isoquinolin-3-ylcarbamate (0.27 g, 43%).
