Reaction Steps

A solution of (S)-tert-butyl 2-((S)-1-cyano-2-(4-(3-(2-methoxyethyl)-2-oxo-2,3-dihydrobenzo[d]oxazol-5-yl)phenyl)ethylcarbamoyl)piperidine-1-carboxylate (38 mg) in formic acid (1 mL) was stirred at 50° C. for 10 min. The solvent was removed in vacuo and the residue was purified by flash silica chromatography eluting with 1:24 2M ammonia in methanol/DCM to give, after trituration with diethyl ether, the title compound (27 mg) as a pale yellow solid.
