실험 절차
To a stirred solution of 4-methyl-1-(thiazol-4-yl)-4-(trimethylsilyloxy) pent-2-yn-1-one (0.15 g, 0.56 mmol) in DCM (3 mL) was added PTSA (0.16 g, 0.84 mmol) at RT and the reaction mixture was stirred for 1 h. The reaction mixture was diluted with water (10 mL), the organic layer was washed with a saturated NaHCO3 solution, water, dried over Na2SO4, filtered and then concentrated in vacuo to afford 4-hydroxy-4-methyl-1-(thiazol-4-yl) pent-2-yn-1-one (0.12 g, crude) as an oil.
