2-Amino-4-methylthiazole → HCID 44313067, compound

Participants

Reaction Steps

In 170 ml of benzene, 4.45 l g (0.035 mole) of 3,3-dimethylglutaraldehyde was combined with 3.96 (0.035 mole) of 2-amino-4-methylthiazole under nitrogen. The reaction mixture was brought to reflux and water azeotroped off via a Dean-Stark trap. After 21 hours 0.20 g (0.001 mole) of p-toluenesulfonic acid monohydrate was added to the reaction mixture and heating continued an additional 5 hours after which the solvent was evaporated in vacuo. The crude product was purified by silica gel flash chromatography eluting with a 1% ethyl acetate/hexane solution. The eluate was evaporated in vacuo to yield 2.67 g of the title compound as a clear liquid.
