(2-(4-Fluorophenyl)ethyl)(methyl)amine → 5-Bromo-thiophene-3-carboxylic acid [2-(4-fluorophenyl)-ethyl]-amide

Participants

Reaction Steps

To a solution of 5-bromo-thiophene-3-carboxylic acid (5 g) and [2-(4-fluorophenyl)-ethyl]methyl-amine (the compound of Preparation Example 14) (3.7 g) in dichloromethane (150 mL) was added 1-Ethyl-3-(3-dimethylamino propyl)-carbodiimide.hydrochloride (5.1 g) was added. After stirring for 1.5 hours, the residue resulting from evaporation of the reaction solution in vacuo was purified by silica gel column chromatography (hexane/ethyl acetate), and the title compound (6 g) was obtained as a colorless oily matter.
