Versuchsvorschrift

A solution of 9-phenylnonanoic acid (1.934 g) and N,N'-carbonyldiimidazole (1.34 g) in dry dichloromethane (20 ml) was stirred at 20° for one hour and a solution of 3,4-dimethoxybenzeneethanamine (1.4 ml) in dry dichloromethane (10 ml) then added. The mixture was stirred at 20° for 18 hours and water added. The organic phase was separated, washed with dilute hydrochloric acid, aqueous sodium bicarbonate and brine, dried over magnesium sulphate and evaporated to leave a solid. Crystallisation from 2-propanol gave the amide as colourless prisms (2.7 g); mp, 117°-119°.
