Reaction Steps

A solution of 4-(3-chloro-propoxy)-benzamide (0.5 g, 2.34 mmol, 1 eq) and methyl 2-chloro-3-oxobutanoate (0.7 ml, 5.62 mmol, 2.4 eq) in ethanol (5 ml) is heated at 110° C. in a sealed tube for 24 h. The mixture is concentrated, taken up in dichloromethane and washed with water. The organic phase is dried over magnesium sulfate and concentrated. The residue is purified by chromatography over silicagel (eluent: dichloromethane) to afford 0.7 g of methyl 2-[4-(3-chloropropoxy)phenyl]-4-methyl-1,3-oxazole-5-carboxylate ax60 as a pale yellow solid.
