実験手順

The title compound was prepared by a similar method to example 3 from (2R,3R,4S,5R)-2-{2-(aminomethyl)-6-[(2,2-diphenylethyl)amino]-9H-purin-9-yl}-5-(methoxymethyl)-tetrahydro-3,4-furandiol (example 1) (110 mg, 0.22 mmol), benzenesulfonyl chloride (36 mg, 0.20 mmol) and triethylamine (0.1 ml, 0.72 mmol) to afford the title compound as a solid (100 mg). MS: 631 (MH+).
