4-Methylphenyl isocyanate → HCID 9907392, compound

Participants

Reaction Steps

p-Tolyl isocyanate (0.058 mL, 0.46 mmol) was added to a solution of 2-methoxy-5-(difluoromethanesulfonyl)aniline (0.100 g, 0.42 mmol) in EtOAc (0.5 mL) and the reaction mixture was stirred at room temp. for 3 d. The resulting precipitate was filtered and washed with Et2O to provide the title compound as a white solid (0.092 g): 1H-NMR (CDCl3) δ 2.22 (s, 3H), 4.01 (s, 3H), 7.01-7.36 (m, 6H), 7.54 (dd, J=2.4, 8.6 Hz, 1H), 8.57 (s, 1H), 8.79 (d, J=2.6 Hz, 1H), 9.33 (s, 1H); EI-MS m/z 370 (M+).
