反応手順

A mixture of Example N (2 g, 0.73 mmol) and 1-naphthylisocyanate (0.124 g, 0.73 mmol) in dry CH2Cl2 (4 ml) was stirred at RT under N2 for 18 h. The solvent was removed in vacuo and the crude product was washed with ethyl acetate (8 ml) and dried in vacuo to yield 1-{3-tert-butyl-1-[3-(carbamoylmethyl)phenyl)-1H-pyrazol-5-yl}-3-(naphthalene-1-yl)urea as a white solid (0.22 g). mp: 230 (dec.); 1H NMR (200 MHz, DMSO-d6): δ 9.12 (s, 1H), 8.92 (s, 1H), 8.32-8.08 (m, 3H), 7.94-7.44 (m, 8H), 6.44 (s, 1H), 3.51 (s, 2H), 1.31 (s, 9H); MS:
