Reaction Steps
To a solution of (S)-2-{4-[(4-Cyano-pyridine-2-carbonyl)-amino]-3-fluoro-phenyl}-morpholine-4-carboxylic acid tert-butyl ester (73 mg, 171 μmol, Eq: 1.00) in THF (3 ml) was added 4M−HCl in dioxane (0.642 ml, 2.52 mmol, Eq: 15). The reaction mixture was stirred at 60° C. for 5 h. To the cooled mixture was then added ethyl acetate and the suspension was filtered off and dried under high vacuo to give the target compound as a white solid (53 mg, 85%). MS (ISP): 325.2 ([M+H]+).
