Participants

Reaction Steps

Zinc dust (30 g) was added to a solution of the product from Example 36.2 (20 g) in acetic acid (300 ml) with cooling to control the exotherm. The resulting mixture was then stirred for 2 h, filtered, and the filtrate was concentrated to dryness. The residue was partioned between chloroform and aqueous sodium bicarbonate, the organic layer was dried and then concentrated to dryness to give a solid residue of 2,4-dibenzyloxypyrrolo[3,2-d]pyrimidine (15.2 g)
