Reaction Steps
Ethyl 5-(2-aminopyrimidin-4-yl)-2-(5-chloro-2-ethylphenyl)-1H-pyrrole-3-carboxylate (450 mg, 1.21 mmol) in DMF (7.5 mL) was treated with N-bromosuccinimide (216 mg, 1.21 mmol). The mixture was stirred overnight at room temperature, then poured into water, extracted with EtOAc (2×30 mL). The separated organic phase was dried over sodium sulfate and the solvent evaporated. Crystallization from diethyl ether afforded the title compound (420 mg, 77%).
