Product 1

HCID 235183374-Amino-7-[3,5-bis-o-(2,4-dichlorophenylmethyl)-2-c,2-o-dimethyl-beta-d-ribofuranosyl]-7h-pyrrolo[2,3-d]pyrimidine

Procedure

To the compound from Step A (735 mg, 1.16 mmol) was added methanolic ammonia (saturated at 0° C.) (20 mL). The mixture was heated in a stainless steel autoclave at 80° C. overnight, then cooled and the content evaporated in vacuo. The crude mixture was purified on silica gel using ethyl acetate/hexane as the eluent. Fractions containing the product were pooled and evaporated in vacuo to give the desired product (504 mg) as colorless foam.
