실험 절차

A solution of 200 mg. of 5-(2-furoyl)-1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1-carboxylic acid in 5 ml. of dichloromethane is treated with an excess of ethereal diazomethane, and the reaction mixture is maintained at room temperature for 30 minutes. The solvents and excess reagent are eliminated under reduced pressure and the residue crystallized from ethyl acetate-methanol, to yield methyl 5-(2-furoyl)-1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1-carboxylate.

후처리

  1. customthe residue crystallized from ethyl acetate-methanol
