Reaction Steps

(4-bromophenyl)methyl cyanamide (0.100 g, 0.47 mmol) tetrakis(triphenylphosphine)palladium(0) (0.050 g, 0.043 mmol), N-methyl-5-cyanopyrroleboronic acid (0.150 g, 1 mmol), potassium carbonate (0.345 g, 2.5 mmol) and dimethoxyethylether/water 3:1 were placed in a microwave reaction vial fitted with a septa. The vial was then filled with a continuous flow of nitrogen. Using microwave assisted conditions, the mixture was heated to 10° C. for 15 minutes. The mixture was poured into water, extracted with ethyl acetate, the ethylacetate dried over magnesium sulfate, and evaporated in vacuo. The residue was flash chromatographed using 9/1 Hexane/ethylacetate to give [4-(5-cyano-1-methyl-1H-pyrrol-2-yl)phenyl]methylcyanamide (0.030 g, 27%). HPLC purity 100% at 210-370 nm, 10 min.; the Xterra™ RP18 instrument, 3.5μ, 150×4.6 mm column, 1.2 mL/min., 85/15-5/95 (Ammon. Form. Buff. Ph=3.5/ACN+MeOH) for 10 min., hold 4 min. HRMS: calcd for C14H12N4+H+, 237.11347; found (ESI, [M+H]+), 237.1127.
