Participants

Reaction Steps

To a solution of 5-[4-(2,6-Dichloro benzyl)-piperazine-1-yl]-4-methyl-benzofuran-2-carboxylic acid (0.07 g, 0.00017 mol) in anhydrous DMF (275 ml) was added diisopropyl ethyl amine (0.08 ml, 0.0005 mol) and morpholine (0.16 ml, 0.00018 mol) under nitrogen atmosphere. The reaction mixture was stirred for 15 minutes, added Py-BOP (0.11 g, 0.0002 mol) and stirred for 1 hour. The completion of the reaction was confirmed by TLC. The reaction mixture was quenched into ice water. The solid separated was filtered. After drying under vacuum, the crude product was isolated as white solid. The crude product was purified by Prep HPLC using a Zorbax C-18 column with mobile phase 0.1% trifluoroacetic acid in water (A)/Acetonitrile (B) with a flow rate of 20 ml/min to yield {5-[4-(2,6-dichlorobenzyl)piperazine-1-yl]-4-methyl-benzofuran-2-yl}-morpholin-4-yl-methanone (35 mg, 43%).
