实验步骤: To a solution of 100 mg (0.651 mmol) of 4-chloro-7H-pyrrolo[2,3-d]pyrimidine dissolved in 3.0 mL of THF was added 0.10 mL (0.818 mmol) of cyclohexylmercaptan and 100 mg (0.847 mmol) of 95% potassium tert-butoxide and the resulting mixture heated at reflux for 3.5 hr. After cooling to room temperature, the reaction mixture was acidified to pH 1 with 2 N HCl and concentrated in vacuo. The residue was then partitioned between ethylacetate and 1 N HCl. The aqueous layer was extracted with ethyl acetate, the ethyl acetate layers were combined, washed with brine, dried over MgSO4, filtered, and evaporated in vacuo. The crude product was purified by silica-gel chromatography (1:3 ethylacetate/hexanes) providing 34 mg (22%) of the title compound as a white solid. Mp 162-163° C. 1H NMR (400 MHz) d: 1.22-1.36 (m, 1H), 1.45-1.64 (m, 5H), 1.75-1.79 (m, 2H), 2.12-2.14 (m, 2H), 4.18-4.20 (m, 1H), 6.50 (d, 1H, J=3.7 Hz), 7.19 (d, 1H, J=3.5 Hz), 8.61 (s, 1H), 10.0 (br s, 1H). LRMS: 234 (M+1). the resulting mixture heated at reflux for 3.5 hr concentrated in vacuo The residue was then partitioned between ethylacetate and 1 N HCl The aqueous layer was extracted with ethyl acetate washed with brine dried over MgSO4 filtered evaporated in vacuo The crude product was purified by silica-gel chromatography (1:3 ethylacetate/hexanes)
