4-Chloromethyl-2-methylthiazole (0.6 g, 4 mmol) was added to aminoacetaldehyde diethyl acetal (5 mL, 10 equivalents) dissolved in tetrahydrofuran (15 mL) at 25° C., and the mixture was stirred for 16 h. The solvents were evaporated and the excess aldehyde was distilled from the crude mixture. The crude residue was purified using dichloromethane—dichloromethane/10% methanol to give 0.76 g (76%) of the title compound.
