4-(Benzo(b)thienyl)acetic acid → HCID 3087825, compound

Participants

Reaction Steps

A mixture of 0.5 g of 4-thianaphthene-acetic acid, 0.422 g of carbonyldimmidazole and 20 ml of tetrahydrofuran was stirred for one hour and then a solution of 0.432 g of the product of Step B in 5 ml of tetrahydrofuran was slowly added thereto. The mixture was stirred for 31/2 hours and the tetrahydrofuran was distilled off under reduced pressure. The residue was taken up in 100 ml of ether and the solution was washed with aqueous saturated sodium bicarbonate solution, then with aqueous saturated sodium chloride solution, dried and evaporated to dryness under reduced pressure to obtain 0.61 g of trans (±)- N-[2,3-dihydro-2-(pyrrolidin-1-yl)-1H-inden-1-yl]-N-methyl-4-benzo[b]thiophene-acetamide in the form of an oil.
