Participants

Reaction Steps

To a solution of tert-butyl 3-cyclopropyl-2-[[5-cyclopropyl-4-(2,2,2-trifluoroethoxy)pyridine-2-carbonyl]amino]-2-methyl-propanoate (example 186c, 103 mg, 233 μmol) in dichloromethane (0.5 ml) was added TFA (159 mg, 108 μl, 1.4 mmol). The reaction mixture was stirred at room temperature for 14 hours. Volatiles were removed in vacuo and the residue was dissolved in a mixture of dichlormethane and toluene followed by evaporation to dryness. The procedure was repeated twice until a precipitate formed. The precipitate was dried under high vacuum to yield the title compound (95 mg) as a crude solid which was used without any purification. MS (ESI, m/z): 387.5 (M+H+).
