Reaction Steps

To a mixture of methyl 5-bromolevulinate (1.22 g), water (5.2 ml) and ethanol (2.6 ml) was added ammonium dithiocarbamate (642 mg) at room temperature. After stirring at room temperature for 2 hours, the resulting crystal was collected by filtration and washed with a cold mixture of water and ethanol at first and diisopropyl ether (×2) to give 4-(2-methoxycarbonylethyl)-2-mercaptothiazole (0.61 g).
