Reaction Steps

Mix methyl 4-iodo-1H-pyrrole-2-carboxylate (1.5 g, 5.98 mmoles), 4,4,5,5-tetramethyl-2-(prop-1-en-2-yl)-1,3,2-dioxaborolane (3.01 g, 17.98 mmoles) 1,1′-bis(di-tert-butylphosphino)ferrocene (dtbpf) (0.3 g, 0.06 mmoles), tris(dibenzylideneacetonyl)bis-palladium (Pd2(dba)3) (0.3 g, 0.06 mmoles), tripotassium phosphate (2.54 g, 11.95 mmoles) and methanol (12 mL). Heat the mixture in a sealed tube in a microwave at 140° C. for 30 minutes. Cool, filter the reaction mixture and wash sinter with methanol, evaporate the filtrate under reduced pressure and chromatograph on silica eluting with isohexane/dichloromethane (gradient elution, 100:0 to 0:100). Evaporate the fractions containing product to give methyl 4-(prop-1-en-2-yl)-1H-pyrrole-2-carboxylate. (0.679 g, 68.79% yield). MS (m/z): 166.1 (M+1).
