Reaction Steps

Cinnamyl bromide (3.04 g) was added to a stirred solution of 4-mercapto-1-β-D-ribofuranosylpyrazolo[3,4-d]-pyrimidine (4.0 g) and potassium carbonate (2.13 g) in N,N-dimethylformamide. The solution was heated (40° C. on an oil bath) for 2 hours. After cooling the reaction mixture was poured into water (0.6 l) and the resultant precipitate was collected and washed with water. The 4-cinnamylthio-1-β-D-ribofuranosylpyrazolo[3,4-d]pyrimidine so obtained was recrystallised from methanol, washed with water and dried (in vacuo at 55° C.), yield 3.2 g, m.p. 165°-166° C.
