Procedure

Methyl 9-isobutyl-8-oxo-2-(3-(triisopropylsilyloxy)phenyl)-8,9-dihydro-7H-purine-6-carboxylate. Methyl 5-amino-6-(2,3-dihydro-1H-inden-1-ylamino)-2-(3-(triisopropylsilyloxy)phenyl)pyrimidine-4-carboxylate (0.300 g, 0.635 mmol) and 1,1′-1,1′-carbonyldiimidazole (0.411 g, 2.54 mmol) in dichloromethane (25 mL) were reacted according to General Procedure F. The solution was condensed under reduced pressure and partitioned between water and ethyl acetate (3×). Organic fractions were combined and dried over magnesium sulfate, filtered and solvent removed under reduced pressure. The crude solid was diluted with methanol (15 mL) and sonicated. The resulting precipitate was filtered to afford the title compound (0.185 g, 85%). MS (ESI) m/z 268.2 [M+1]+.
