Oxalyl chloride (19.5 mL, 0.21 mol) was added slowly to a 0° C. solution of 1,2-dimethyl-4-phenyl-pyrrole (30.5 g, 0.178 mol) in dry dichloromethane (150 mL). The reaction mixture was warmed to room temperature and stirred for 1 h. The solvent was removed in vacuo to afford 2-(1,5-dimethyl-3-phenyl-pyrrol-2-yl)-2-oxo-acetyl chloride (46 g, 99%) as a brown oil.
