N-Bromosuccinimide (6.2 g, 34.9 mmol) is added to a solution of 1-methyl-1H-pyrrole-2-carbonitrile (3.7 g, 34.9 mmol) in N,N-dimethylformamide (150 mL). The solution is stirred for 15 hours at ambient temperature. Another amount of N-bromosuccinimide (2.0 g, 11 mmol) is added and the mixture is stirred for 3 hours. The product is purified by chromatography over silica gel (ethyl acetate/heptane gradient) to obtain the expected product in the form of a solid.
