2-Bromo-2',5'-dimethoxyacetophenone → [4-(2,5-Dimethoxy-phenyl)-thiazol-2-yl]-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-amine

Participants

Reaction Steps

The title compound was prepared in analogy to example 1 step e) from 88 mg (0.33 mmol) 2-bromo-2′,5′-dimethoxyacetophenon and 79 mg (0.3 mmol) [3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-thiourea. The crude reaction was diluted with diethyl ether and stirred for 15 minutes at room temperature. The product was filtered off and dried to yield 124 mg (98%) [4-(2,5-dimethoxy-phenyl)-thiazol-2-yl]-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-amine as a light green solid. MS ISP (m/e): 423.2 (100) (M+H)+. 1H NMR (DMSO-D6, 250 MHz): δ (ppm)=10.68 (s, 1H), 9.28 (s, 1H), 7.99 (s, 1H), 7.72 (s, 1H), 7.69 (d, 1H), 7.54 (s, 1H), 7.52 (d, 1H), 7.28 (d, 1H), 7.07 (d, 1H), 6.89 (dd, 1H), 3.92 (s, 3H), 3.88 (s, 3H), 3.75 (s, 3H), 2.34 (s, 3H).
