HCID 665989975-Methylthiazole-4-carbohydrazide

Procedure

A mixture of 1,1-dimethylethyl 2-[(5-methyl-1,3-thiazol-4-yl)carbonyl]hydrazinecarboxylate (544 mg, 2.114 mmol) in HCl (2643 μl, 10.57 mmol) (4M in 1,4-dioxane) was stirred at room temperature under an atmosphere of argon for 17 hours (overnight). After this time, the reaction mixture was concentrated under reduced pressure to give an off-white coloured solid of desired material in 162 mg.
