Reaction Steps

To a solution of formic acid 3-[2(R)-(3-chloro-4-methanesulfonyl-phenyl)-2-(pyrazin-2-ylcarbamoyl)-ethyl]-cyclopentyl ester (375 mg, 0.83 mmol) in methanol (50 mL) at 0° C. was bubbled ammonia gas for 15 min. The resulting reaction solution was stirred at 0° C. for 15 min. The solvent was removed in vacuo. Flash chromatography (Merck Silica gel 60, 70-230 mesh, 1-5% methanol/methylene chloride) afforded 2(R)-(3-chloro-4-methanesulfonyl-phenyl)-3-(3-hydroxy-cyclopentyl)-N-pyrazin-2-yl-propionamide (260 mg, 62.5%) as an off-white solid.
