Reaction Steps
A solution of n-butyllithium (4.32 mL of 1.6 M solution in hexane, 6.92 mmol) was added to 5-bromopyrimidine (1.0 g, 6.29 mmol) in THF (10 mL) at −78° C. with stirring under N2. After being stirred at −78° C. for 1 h, a solution of 1,4-cyclohexanedione mono-ethylene ketal (0.982 g, 6.29 mmol) in THF (10 mL) was added to the lithiated compound solution via syringe and stirred for 4 h at −78° C. Water (5 mL) was added, and the reaction mixture was warmed to room temperature and extracted using EtOAc (3×). The combined organic layers were dried (MgSO4), filtered, concentrated in vacuo and chromatographed to yield 0.18 g of 8-pyrimidin-5-yl-1,4 dioxaspiro[4,5]decan-8-ol in 12% yield. MS (E) calcd: (M+H)+=237.1; found: 237.2.
