Procedure

3-Chloro-4-(thiazol-2-ylmethoxy)-phenylamine is prepared by added Zn dust (55.9 g, 856 mmol) to a mixture of 2-(2-chloro-4-nitro-phenoxymethyl)-thiazole (47.0 g, 190 mmol) in 5:1 MeOH:saturated aqueous NH4Cl solution (600 ml). After 2 h, the reaction mixture is filtered, and the filtrate concentrated. The resulting solid is triturated with water to give 3-chloro-4-(thiazol-2-ylmethoxy)-phenylamine (35.2 g, 85%).
