Procedure

2-Methyl-4-(chloromethyl)thiazole (2.24 g) was treated with ethanolamine (11.6 mL, 10 equivalents) in dichloromethane at 25° C. for 16 hrs. The solvent was evaporated and the residue partitioned between ethyl acetate and brine. The organic layer was separated and extracted with ethyl acetate (5×). The organic layers were combined and washed with brine, dried over Na2SO4, and the solvents were evaporated to give 2.4 g (85%) of title compound.
