Versuchsvorschrift
N1-methyl-4-nitro-benzene-1,2-diamine (2.0 g, 12.0 mmol) and methyl isothiocyanate (0.90 ml, 13.2 mmol) were coupled using the procedure of example one part B to give the title compound as a yellow solid (1.32 g, 53%). 1H NMR (300 MHz, d6-DMSO) δ 7.98 (d, J=2.1 Hz, 1H), 7.90 (dd, J=8.7 and 2.4 Hz, 1H), 7.32 (d, J=8.7 Hz, 1H), 7.15 (m, 1H), 3.55 (d, 3H), 2.95 (d, J=4.5 Hz, 3H).
