실험 절차
A solution of tert-butyl 4-(4-{[4-carbamoyl-2-(naphthalen-2-ylamino)thiazol-5-yl]carbamoyl}benzy)piperazine-1-carboxylate (0.025 g, 0.04 mmol) in 4N HCl-dioxane (5 mL) was stirred for 2 hrs at rt under N2-atmosphere. The solvent was evaporated in vacuo, and the residue was washed with ether and purified by silica gel column chromatography eluted with 50% EtOAc in hexane to give 0.013 g (68% yield) of the titled compound.
