Procedure

A solution of (R)—N-(2-(1-azidopropan-2-yl)-6-methyl-1-oxo-1,2-dihydroisoquinolin-5-yl)-2-(3-fluoro-4-(trifluoromethyl)phenyl)acetamide (0.6 g, 0.001 mol) in ethanol (50 mL, 0.8 mol) was heated at 85° C. A solution of ammonium chloride (0.6 g, 0.01 mol) in water (15 mL, 0.83 mol) was added followed by iron powder (0.6 g, 0.01 mol). The mixture was stirred at the same temperature for 3 hours and poured onto dichloromethane (200 mL) and extracted. The residue was purified by reverse phase HPLC to afford the desired product as a white solid (232 mg, yield 50%).
