Reaction Steps

To a stirred solution of 1-(4-chlorophenyl)-4-methyl-4-(trimethylsilyloxy)pent-2-yn-1-one (3.7 g, 12.50 mmol) in DCM (20 mL) was added PTSA (2.87 g, 15.01 mmol) at RT. The reaction mixture was stirred for 1 h and diluted with water (10 mL). The combined organic layers were washed with a saturated NaHCO3 solution and water, dried over Na2SO4, filtered, and then concentrated in vacuo to afford 1-(4-chlorophenyl)-4-hydroxy-4-methylpent-2-yn-1-one (2.40 g) as a pale red oil.
