実験手順
In a similar manner to Example 49 reaction of 2-(2-propoxyphenyl)purin-6-one (0.81 g) with chlorosulphonic acid (4.5 ml), followed by reaction with methylamine in industrial methylated spirit (33%, 50 ml) yielded the title compound, 0.49 g, m.p. 245-246° C. (recrystallised twice from aqueous ethanol).
