A solution of 4-(3-chloropropoxy)benzenecarbothioamide ax71 (0.3 g, 1 eq, 1.31 mmol) in ethyl alcohol (5 ml) is treated with 1,3-dichloro-1-ethoxy-propane (0.4 ml, 2.7 eq, 3.6 mmol) and the mixture is stirred at 110° C. during 4 h. The mixture is then poured into dichloromethane (10 ml) and is washed with water. The organic phase is dried over magnesium sulfate and concentrated. Purification by chromatography over silicagel (eluent: dichloromethane) affords 120 mg of 2-[4-(3-chloropropoxy)phenyl]-1,3-thiazole i88.
