Procedure
2-(S)-{[Benzofuran-2-ylmethyl]-amino]-methyl}-pyrrolidin-1-carboxylic acid tert-butyl ester 0.33 g (0.28 mmol), 3,4,5-trimethoxy-benzoyl chloride 65 mg (0.28 mmol) and triethylamine 0.04 mL (0.28 mmol). After 1 hour, saturated sodium bicarbonate added and the mixture extracted with dichloromethane, combined organic layer, dried over magnesium sulfate, filtered, and concentrated under vacuum. Purification over silica gel chromatography, elution ethyl acetate-hexane 5.5-4.5, gave 100 mg of light yellow oil.
