Versuchsvorschrift

This compound was isolated as a byproduct from a two step preparation as described: A): 2-(1-benzothien-3-ylmethyl)-7-isobutyl-3-(1-methyl-1H-pyrrol-2-yl)-2H-pyrazolo[3,4-d]pyrimidine-4,6(5H,7H)-dione was prepared starting from 6-hydrazino-1-isobutylpyrimidine-2,4(1H,3H)-dione and condensing first with 1-benzothiophene-3-carbaldehyde, followed by 1-methyl-1H-pyrrole-2-carbaldehyde.
