Procedure
A solution of 1 equivalent 4-diisopropylcarbamoyl-benzoyl chloride (prepared from N,N-diisopropyl-terephthalamic acid and thionyl chloride) in dichloromethane is added dropwise at RT in the course of 10 min. to a solution of 1 equivalent of (3R,4R)-3-(3-ethoxy-4-methoxy-phenyl)-tetrahydro-pyran-4-ylamine in dichloromethane and 1.1 equivalents of triethylamine. After stirring for about 2 h, the mixture is extracted with saturated sodium hydrogencarbonate solution, and the organic phase is washed a further two times with water and dried over sodium sulfate. The viscous residue remaining after concentration is purified by column chromatography on SiO2 (dichloromethane/ethyl acetate 85/15 vol/vol). The main product fraction concentrated in vacuo affords a brownish solid foaming residue which is used for the next reaction step without further treatment.
