Participants

Reaction Steps

(2R,3R,4S,5R)-2-{2-(Aminomethyl)-6-[(2,2-diphenylethyl)amino}-9H-purin-9-yl}-5-(methoxymethyl)tetrahydro-3,4-furandiol (example 1) (200 mg, 0.39 mmol) was dissolved in stirred methanol (10 ml) and N,N-dimethylacrylamide (40 mg, 0.39 mmol) added. The reaction mixture was stirred for 120 hr at room temperature and then 50° C. for a further 24 hr. More N,N-dimethylacrylamide (9 mg, 0.1 mmol) was added and the reaction mixture was heated at 50° C. for 30 hr. A further portion of N,N-dimethylacrylamide (10 mg, 0.1 mmol) was added and the reaction mixture heated to 50° C. for a further 24 hr. The solvent was then removed under reduced pressure and the residue purified by column chromatography on silica gel eluting with a solvent system of dichloromethane:methanol:ammonia (94:4:0.2) increasing in polarity to (93:7:0.3) to give the title compound (100 mg) as a foam. MS: 590 (MH+).
