Sodium Carbonate → HCID 9944717, compound

Participants

Reaction Steps

450 mg (1.15 mmol) of 2-(4-fluorophenyl)-3-(pyridin-4-yl)-4-(1,2,3,6-tetrahydropyridin-4-yl)-1H-pyrrole dihydrochloride [prepared as described in Example 10 above] were suspended in a mixture of 25 ml of xylene and 2 ml of methanol and 450 mg of 10% palladium on carbon and 320 mg (2.30 mmol) of sodium carbonate were added to the suspension. The resulting mixture was heated under reflux for 4 hours. At the end of this time, the reaction mixture was filtered and the resulting filtrate was concentrated by evaporation under reduced pressure. The residue thus obtained was purified by chromatography on a silica gel column using a 10:1:1 by volume mixture of ethyl acetate, methanol and isopropylamine as the eluant to give 192 mg (yield 53%) of the title compound as a pale yellow powder.
