実験手順
To a solution of 7-allyl-1-(3-(tert-butyldimethylsilyloxy)propyl)-8-chloro-3-ethyl-1H-purine-2,6(3H,7H)-dione (3.8 g, 8.92 mmol) in ethanol (20 mL) was added concentrated HCl (2 mL). The mixture was stirred at room temperature for 0.5 h. The mixture was concentrated and partitioned between ethyl acetate and saturated sodium bicarbonate. The organic phase was washed with brine and dried over sodium sulfate, and concentrated to give 7-allyl-8-chloro-3-ethyl-1-(3-hydroxypropyl)-1H-purine-2,6(3H,7H)-dione (3.8 g) as yellow oil, which was used without purification. LCMS retention time 0.999 min; LCMS MH+ 313.
