Procedure
The mixture of N-(9-chloro-3,4-dihydro-2H-1,5-benzodioxepin-7-ylmethyl)-2-methylpropan-1-amine (84 mg), 4-benzyl-piperazine-1,2-dicarboxylic acid 1-tert-butyl ester (100 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (90 mg), and dimethyl aminopyridine (53 mg) in dichloromethane (8 ml) was stirred at room temperature overnight. After addition of water (8 ml) the reaction mixture was extracted with ethyl acetate (8 ml×3). The organic layers were combined, washed with saturated sodium bicarbonate, water and brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The crude product was purified by column chromatography on silica (20% ethyl acetate in hexane) to give a resin: MS (m+1)=572.4.
