Reaction Steps

A solution of 5-methyl-1,3-thiazole-2-carboxylic acid (500 mg, 3.49 mmol) in dry dichloromethane (DCM) (17.500 ml) was stirred at room temperature under an atmosphere of argon. EDC (803 mg, 4.19 mmol) and HOBT (267 mg, 1.746 mmol) were added to the stirred solution. After 15 minutes, 1,1-dimethylethyl hydrazinecarboxylate (554 mg, 4.19 mmol) was added to the stirred solution. The resulting solution was stirred for 18 hours. After this time, the solution was diluted with DCM (approx. 50 ml) and washed with water (2× approx. 20 ml). The organic extracts were dried over MgSO4, filtered and concentrated under reduced pressure to give a yellow coloured oil of desired product in 451 mg.
