PROCEDURE

实验过程

[(3aR,4R,6R,6aR)-6-(6-Bromo-9H-purin-9-yl)-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl]methyl acetate (0.1 g, 0.242 mmol), 3-(1-H-pyrazole-1-yl)phenylboronic acid (0.137 g, 0.726 mmol), potassium phosphate (0.154 g, 0.726 mmol), and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex dichloromethane (1:1) (0.040 g, 0.048 mmol) were placed in an oven-dried microwave vial and degassed with argon. Anhydrous dioxane (1.5 mL) was added and the reaction was heated to 150° C. for ten minutes in the microwave. The mixture was filtered through a pad of Celite washing with dichloromethane then concentrated. The residue was taken up in dichloromethane and purified on a prep plate using 60% ethyl acetate/hexanes as developing solvent to give the title compound as a yellow solid (0.061 g 53%).
