実験手順

DIPEA (0.26 mL, 1.5 mmol) was added to a solution of 3-[(1-methylethyl)oxy]-5-[(4-methyl-5-oxo-2,3,4,5-tetrahydro-1,4-benzoxazepin-8-yl)oxy]benzoic acid (185 mg, 0.5 mmol), 1,1-dimethylethyl 3-amino-1H-pyrazole-1-carboxylate (110 mg, 0.6 mmol) and HATU (247 mg, 0.65 mmol) in DMF (2 mL) and the mixture stirred at RT for 16 hours. The mixture was poured onto water (30 mL), extracted with ethyl acetate (3×15 mL), the combined organic extracts washed with 1N citric acid, saturated sodium hydrogen carbonate, brine, dried (MgSO4) and evaporated in vacuo. The residue was chromatographed on silica, eluting with 60% ethyl acetate in isohexane, to give the desired compound (32 mg). 1H NMR δ (CDCl3): 1.3 (d, 6H), 1.55 (s, 9H), 3.15 (s, 3H), 3.5 (t, 2H), 4.3 (t, 2H), 4.5 (m, 1H), 6.5 (s, 1H), 6.7 (m, 2H), 7.1 (d, 1H), 7.8 (d, 1H), 7.95 (d, 1H), 8.7 (s, 1H); m/z 535 (M−H)−
