Procedure
To a stirred mixture of 1.91 g (5.5 mmol) of 4,5-dichloro-2-(3,4-dichlorophenyl)-1-(2-propynyl)pyrrole-3-carbonitrile in 500 mL of methanol is added 69 mL of 10% aqueous sodium hydroxide and then 0.70 g (2.7 mmol) of iodine. The mixture is stirred for 12 hours and then acidified and diluted with 200 mL of water. The precipitated solids are collected and recrystallized from methanol to afford 0.51 g while crystals, m.p. 115°-116° C.
