Versuchsvorschrift

This compound was made in two steps following the procedure described above, starting with 6-hydrazino-1-isobutyl-3-methylpyrimidine-2,4(1H,3H)-dione, and condensing first 5-chloro-1H-indole-3-carbaldehyde, followed by 4-acetyl-1-methyl-1H-pyrrole-2-carbaldehyde. The isolated 3-(4-acetyl-1-methyl-1H-pyrrol-2-yl)-2-[(5-chloro-1H-indol-3-yl)methyl]-7-isobutyl-5-methyl-2H-pyrazolo[3,4-d]pyrimidine-4,6(5H,7H)-dione was treated sodium borohydride in anhydrous THF and heated at 80° C. for 1 h and the product was isolated by aqueous workup. The presence of alcohol peak (δ 64.8 ppm)was confirmed by 13C NMR (CDCl3)— no ketone peak at (δ 193.5 ppm).
