Participants

Reaction Steps

A solution of N2-butyl-8-(methoxy)-9-[2-(tetrahydro-2H-pyran-2-yl)ethyl]-9H-purine-2,6-diamine (54 mg) in methanol (1 ml) was treated with 4N HCl in dioxin (0.5 ml) and stood for 1.5 h. The solvents were stripped and the residue treated with water and made basic with saturated aqueous sodium bicarbonate. The precipitated material was filtered, washed with water and dried to give the title compound as a solid, yield 22.5 mg.
