Reaction Steps

Benzoyl pyrrolinone ester 17 (74 mg) was irradiated with microwave radiation (at 300 Watts) without solvent, heating to 200° C. for 10 minutes. The crude product was then allowed to cool, methanol was added and the solid filtered off and washed with methanol. This gave the furopyrrole 18 as an orange solid (34 mg, 52%), m.p 230-232° C. (lit. [H. Langhals, T. Grundei, T. Potrawa, K. Polborn, Liebigs Ann. Chem., 1996, 679] 230-232° C.). δH (CDCl3) 8.48-8.42 (2H, m, Ar—H) and 7.61-7.20 (13H, m, Ar—H)
