Participants

Reaction Steps

A solution of 10 ml of aqueous hydriodic acid, 10 ml of acetic anhydride and 2 ml of 50% hypophosphorous acid containing 548 mg of 2,4-dimethyl-3acetyl pyrrole was stirred magnetically while a solution of 0.6 ml of benzaldehyde in 5 ml of acetic anhydride was slowly added over 20 mins. The solution was stirred for 10 mins, then poured into water. The crude product which separated was recrystallized from acetone (thimble) as nearly colourless irregular plates (85%, m.p. 165.5°-167° C. after a partial change to prismatic rods above 165° C.
