In a procedure analogous to that of Example 9, by using 1.49 g of 6-methylaminopurine, 1.38 g of potassium carbonate, 50 ml of N,N-dimethylacetamide and 3.92 g of 2,6-dichlorobenzyl chloride, there was obtained 1.9 g of 9-(2,6-dichlorobenzyl)-6-methylaminopurine as colorless needles (yield: 62%), m.p. 219°-220° C. NMR spectrum of this product is identical with that of the corresponding compound synthesized in Example 2.
