Reaction Steps
3-Pentanone (0.85 ml) was added to a solution of 548 mg of 2,4-dimethyl-3-acetyl-pyrrole, in 10 ml of aq. hydriodic acid, 10 ml of acetic anydride and 2 ml of hypophosphorous acid. The solution was stirred for 13/4 hours then poured into 200 ml of water to precipitate the product as tiny nearly colourless prisms (651 mg, 79%), m.p. about 186°-189° C. For analysis it was recrystallized from ethanol as colourless plates, m.p. 188.5° C. after a solid phase change at 135°. Anal. Calc. for C13H21NO: C, 75.31; H, 10.21; N, 6.76. Found: C, 75.13; H, 10.04; N, 6.78.
