A solution of methyl (2S)-2-({[(1,1-dimethylethyl)oxy]carbonyl}amino)-5-(4-{[(2-fluorophenyl)methyl]amino}phenyl)-4-pentynoate (D65, 192 mg, 0.450 mmol) in DCM containing 5% TFA (10.5 ml) was stirred at room temperature for 4.5 h. Then 28% NH3 in water was added and the mixture was extracted with DCM. The combined organic layers were dried (Na2SO4), filtered and evaporated to afford the title compound (132 mg). The crude product was used unpurified in the next step. UPLC: 0.56 min, MS: (ES/+) m/z: 327 [MH]+, C19H19FN2O2 requires 326.
