Procedure
The title compound was prepared in analogy to example 1 step e) from 56 mg (0.33 mmol) ethyl 4-chloroacetoacetate and 79 mg (0.3 mmol) [3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-thiourea. The crude product was purified through stirring with diethyl ether yielding 115 mg (98%) {2-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenylamino]-thiazol-4-yl}-acetic acid ethyl ester as an off-white solid. MS ISP (m/e): 373.1 (100) (M+H)+. 1H NMR (DMSO-D6, 250 MHz): δ (ppm)=10.68 (s, 1H), 9.26 (s, 1H), 7.83 (s, 1H), 7.65 (s, 1H), 7.46 (d, 1H), 7.22 n(d, 1H), 6.79 (s, 1H), 4.09 (q, 2H), 3.83 (s, 3H), 3.67 (s, 2H), 2.33 (s, 3H), 1.19 (t, 3H).
