Reaction Steps

To a solution of (2R)-2-methyl-2-(methylsulfonyl)-4-{2-oxo-4-[4-(tetrahydro-2H-pyran-4-yl)phenyl]pyridin-1(2H)-yl}-N-(tetrahydro-2H-pyran-2-yloxy)butanamide (82 mg, 0.15 mmol) in 2-propanol (1.5 mL) was added 1.0 N hydrochloric acid (0.77 mL). The solution was stirred for 1 h. The reaction was concentrated, the residue was triturated with 2-propanol as a white suspension at 50° C. for 30 minutes. A white solid was collected by filtration (75%).
