Procedure
An amount of 0.8 ml of morpholine was dissolved in a two-phase mixture of 40 ml of ethyl acetate and 40 ml of water. Then, 1 gm of crude 8-(2'-methoxy-4'-chlorosulfonylphenyl)-purine hydrochloride was added thereto in batches, under vigorous stirring, and the resulting mixture was heated to 80° C. for two hours. The reaction mixture was concentrated down to one-third of the volume, and the crystals precipitated were subjected to suction filtration and washed with water.
