Procedure

(S)-3-(tert-Butyl-dimethyl-silanyloxy)-2-{2-[2-(2,2,2-trifluoro-ethyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yloxy}-propionic acid methyl ester was dissolved in ammonia in methanol (7 N, 10 mL) and the reaction mixture stirred at RT for 48 hr. The reaction mixture was concentrated in vacuo and the resultant residue subjected to flash chromatography (SiO2, gradient 0-5% methanol in ethyl acetate) to give (S)-3-(tert-Butyl-dimethyl-silanyloxy)-2-{2-[2-(2,2,2-trifluoro-ethyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yloxy}-propionamide as a yellow oil (101 mg, 49% over 2 steps). LCMS: RT=3.78 min, [M+H]+=553
