実験手順

To a solution of tert-butyl {3-[(4-{difluoro[5-(2-methoxyphenyl)-1,3,4-oxadiazol-2-yl]methyl}benzoyl)amino]-1-phenyl-1H-pyrazol-4-yl}carbamate (10 mg) in methylene chloride (2 mL) was added trifluoroacetic acid (1 mL) and the solution was stirred at ambient temperature for 16 hours. The reaction was evaporated to dryness to give N-(4-amino-1-phenyl-1H-pyrazol-3-yl)-4-{difluoro[5-(2-methoxyphenyl)-1,3,4-oxadiazol-2-yl]methyl}benzamide as a yellowish solid. 1H NMR (CD3OD) δ 8.45 (s, 1H), 8.23 (d, J=8.21 Hz, 2H), 7.93 (m, 3H), 7.79 (d, J=7.62 Hz, 2H), 7.64 (m, 1H), 7.52 (t, J=7.62 Hz, 2H), 7.37 (t, J=7.62 Hz, 1H), 7.25 (d, J=8.5 Hz, 1H), 7.14 (t, J=7.62 Hz, 1H), 3.96 (s, 3H); ESIMS calcd 503.2 (M++H), found 503.1 (M++H).
