Versuchsvorschrift

Combine (S)-3-(2-(4-phenyl-4-carboxypiperidin-1-yl)ethyl)-3-(3,4-dichlorophenyl)pyrrolidine (50 g, 112 mmol) and sodium bicarbonate (30 g) in tetrahydrofuran (1300 mL) and water (300 mL). Add portionwise over about 45 minutes, a solution of 3,4,5-trimethoxybenzoyl chloride (26 g, 112 mmol) in tetrahydrofuran (130 mL). After 2 hours, dilute with water (1000 mL). Adjust the pH to about 4 using concentrated aqueous hydrochloric acid to give a solid. Collect the solid by filtration and rinse with water. Triturate the solid with methanol (1300 mL) and water (1300 mL). Filter, rinse with water and dry in vacuo to give the title compound.
