実験手順

To 1-(tert-butoxycarbonyl)-4-[4-methyl-2-(4-pyridyl)-5-thiazolecarbonyl]piperazine (6.40 g) were added methanol (30 ml) and 4N hydrochloric acid in ethyl acetate (30 ml), and the mixture was stirred at room temperature for 30 minutes. The reaction solution was concentrated, and the residue was washed with ether and dried under reduced pressure to give powders of the title compound (5.8 g).
