Procedure
The title compound was prepared in analogy to example 1 step e) from 77 mg (0.33 mmol) 2-chlorophenacylbromide and 79 mg (0.3 mmol) [3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-thiourea. The solvent was evaporated under reduced pressure and the crude reaction was stirred with methylene chloride/diethyl ether/ethanol for 15 minutes at room temperature. The product was filtered off and dried to yield 118 mg (100%) [4-(2-chloro-phenyl)-thiazol-2-yl]-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-amine as a light yellow solid.
