Reaction Steps
To a solution of tert-butyl 2-[[5-cyclopropyl-4-(2,2,2-trifluoroethoxy)pyridine-2-carbonyl]amino]-3,3-dimethyl-butanoate (example 194a, 0.47 g, 1.09 mmol) in dichloromethane (3 ml) was added trifluoroacetic acid (3.73 g, 2.52 ml, 32.8 mmol) and the reaction mixture was stirred at room temperature for 14 hours. Volatiles were removed in vacuo and the residue was dissolved in toluene followed by evaporation to dryness. The procedure was repeated twice to yield the title compound (432 mg) as a crude solid which was used without any purification. MS (ESI, m/z): 373.5 (M−H+).
