Phenyl Isothiocyanate → HCID 59674151, compound

Participants

Reaction Steps

A solution of phenyl isothiocyanate (1.58 ml, 13.2 mmol) and 1-cyclohexyl-3-(2-morpholinoethyl)carbodiimide metho-p-toluenesulfonate (6.6 g, 15.6 mmol) was stirred in pyridine (20 ml) at 90° C. After 2 hours, N1-methyl-4-nitro-benzene-1,2-diamine was added and the reaction was heated overnight. The reaction was cooled and concentrated to a red solid. This was dissolved in EtOAc and washed with water. The organic layer was dried over MgSO4 and concentrated to a red solid. This was stirred in MeOH, filtered, and dried to give the title compound as an orange solid (1.97 g, 62%). 1H NMR (300 MHz, d6-DMSO) δ 8.23 (s, 1H), 8.17 (d, J=1.8 Hz, 1H), 8.02 (dd, J=8.7 and 2.1 Hz, 1H), 7.89 (d, J=8.1 Hz, 2H), 7.50 (d, J=8.7 Hz, 1H), 7.36 (m, 2H), 7.02 (m, 1H), 3.79 (s, 1H) ppm. MS (ESI) m/z=269 [M+H]+.
