Participants

Reaction Steps

As shown in step 7-i of Scheme 7, to a solution of 1,4-dioxaspiro[4.5]decan-8-ol (compound 1021, 1.0 g, 6.32 mmol) in DMF (10 mL) was added NaH (370 mg, 9.25 mmol). The reaction mixture was stirred for 20 minutes before the addition of 2-chloropyrimidine (869 mg, 7.59 mmol). The mixture was stirred for 30 minute at RT and then heated to 100° C. for 9 hours. After cooling, the mixture was diluted with EtOAc, washed with H2O, dried over Na2SO4, concentrated under reduced pressure, and purified by medium pressure silica gel chromatography (0-40% EtOAc/hexanes) to produce 2-(1,4-dioxaspiro[4.5]decan-8-yloxy)pyrimidine (compound 1022) as a colorless oil: 1H NMR (300 MHz, Chloroform-d) δ 8.52 (d, J=4.8 Hz, 2H), 6.92 (t, J=4.8 Hz, 1H), 5.15 (ddd, J=10.7, 6.5, 4.2 Hz, 1H), 4.05-3.87 (m, 4H), 2.14-1.85 (m, 6H), 1.79-1.65 (m, 2H); ESMS (M+H+)=237.12.
