Procedure

To a solution of (4S,2R,3R,5R)-2-aminomethyl-5-[6-(tetrahydrofuran-3-yl)-purin-9-yl]-tetrahydrofuran-3,4-diol acetonide, a compound of formula (11) (100 mg), in ethanol (5 mL) was added triethylamine and 2-chlorobenoxazole, and the mixture was refluxed for 16 hours. The solvent was evaporated and the residue purified by preparative TLC (5% MeOH/DCM) to give (4S,2R,3R,5R)-2-(benzoxazol-2-ylaminomethyl)-5-[6-(tetrahydrofuran-3-yl)-purin-9-yl]-tetrahydrofuran-3,4-diol acetonide, a compound of formula (12).
