2,4-Difluorophenyl isocyanate → HCID 67442237, compound

Participants

Reaction Steps

To a solution of 126 (125 mg, 0.288 mmol) in DCM (6 mL) was added the 2,4-difluorophenyl isocyanate (134 mg, 0.865 mmol) and the reaction mixture was stirred at RT overnight. The reaction mixture was then concentrated and the resultant solid was triturated with acetone and collected by filtration to give title compound 127 (100 mg, 59% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 9.37 (s, 1H), 8.61 (s, 1H), 8.51 (d, J=5.48 Hz, 1H), 8.14 (s, 1H), 8.04 (m, 1H), 7.94 (m, 2H), 7.76 (m, 1H), 7.64 (m, 2H), 7.45 (t, J=8.99 Hz, 1H), 7.35 (m, 1H), 7.22 (m, 1H), 7.06 (m, 1H), 6.63 (d, J=5.48 Hz, 1H), 3.48-3.37 (m, 4H), 1.85 (m, 4H). MS (m/z)=589.546 (M+H)
