A solution of 8-(2-isopropyl-1,3-thiazol-5-yl)-1,4-dioxaspiro[4.5]decan-8-ol (0.714 g, 2.52 mmol) in 15 mL of THF/N HCl (1:1) was stirred overnight at room temperature. The mixture was treated with Na2CO3 to PH 8 and extracted with EtOAc (3×). The combined organic layers were washed with saturated NaCl solution, dried (MgSO4), and concentrated to give 0.65 g of 4-hydroxy-4-(2-isopropyl-1,3-thiazol-5-yl)cyclohexanone in 98% yield. MS (EI) calcd: (M+H)+=240.1; found: 240.0.
