Yield:1240948-77-9 98%

Reaction Conditions:

with palladium 10% on activated carbon;hydrogen in methanol at 20;

Steps:

4 Preparation of 5-(2-fluorophenyl)-1H-pyrrole-3-carbonitrile (Intermediate V-1)

2 g of the intermediate IV-1 was dissolved in 40 ml of methanol, 200 mg of 10% palladium on carbon was added, hydrogen gas was introduced, and the reaction was stirred at room temperature overnight. After the reaction was completed, it was suction filtered with a celite funnel containing celite, and the filtrate was concentrated to give compound of formula V-1, 1.65 g of white solid, yield 98%
