4-Piperidinecarboxamide → 2-[2-(4-Carbamoylpiperidino)ethoxy]bibenzyl

関与物質

反応手順

A solution of 2 g of 2-(2-bromoethoxy)bibenzyl and 1.7 g of 4-piperidinecarboxamide in 20 ml of tetrahydrofuran and 10 ml of water was stirred at 70° C. for 10 hours. The reaction mixture was concentrated and to the residue was added 1 N NaOH aqueous solution. The resultant crystals were filtered, washed well with water and then recrystallized from ethanol to give 1.9 g (82% yield) of 2-[2-(4-carbamoylpiperidino)ethoxy]bibenzyl, m.p. 60°-63° C.
