Participants

Reaction Steps

To an ice-cold mixture of ethyl 2-amino-1,3-thiazole-4-carboxylate (5 g), pyridine (3.36 ml) and dichloromethane (50 ml) was added benzyloxycarbonyl chloride (3.1 ml), and the mixture was stirred at ambient temperature for 1 hour. The reaction mixture was washed with saturated aqueous sodium hydrogen bicarbonate (30 ml), dried over sodium sulfate and concentrated in vacuo. The crystalline residue was collected and washed with diisopropyl ether to give ethyl 2-{[(benzyloxy)carbonyl]amino}-1,3-thiazole-4-carboxylate (5.1 g).
