Procedure

A mixture of 8-dimethylamino-methylene-6,8-dihydro-1-thia-3,6-diaza-as-indacen-7-one (Procedure E, 0.040 g, 0.163 mmol), 4-amino-N-methylacetanilide (0.040 g, 0.244 mmol) in absolute ethanol (5 ml) was heated with stirring at 90° C. for 16 h. The reaction was diluted with ethanol and diethyl ether and the product collected by filtration to yield 0.038 g (64%) of the title compound. 1H NMR (DMSO-d6): δ11.03 (d,1H, J=12.3 Hz), 10.84 (s,1H), 9.23 (s,1H), 8.02 (d,1H, J=12.3 Hz), 7.78 (d,1H, J=8.4 Hz), 7.48 (d,2H, J=8.2 Hz), 7.35 (d,2H, J=8.2 Hz), 7.09 (d,1H, J=8.4 Hz), 3.11 (s,3H), 1.76 (s, 3H); ES−MS m/z 363 (M−H).
