実験手順

To a suspension of 2-(4-chloro-2-methoxyphenyl)ethanamine hydrochloride (Preparation 8; 23.4 g, 105 mmol) in DCM (200 ml) was added triethylamine (16.8 ml, 120 mmol), and the mixture was allowed to stir for 30 minutes (solids did not go into solution). To this was added sequentially 4-(6-chloro-4-(ethoxycarbonyl)chroman-7-yloxy)benzoic acid (Preparation 1; 37.8 g, 100 mmol, 1H-benzo[d][1,2,3]triazol-1-ol hydrate (15.4 g, 100 mmol), and N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (23.1 g, 120 mmol), and the reaction was allowed to stir overnight (all solids went into solution after 2 hours). The reaction was diluted with EtOAc (600 ml) and washed with 600 mL portions of 1M HCl, saturated aqueous bicarbonate, and brine. The organic layer was dried over sodium sulfate, filtered, and concentrated. The residue was taken up in hot ethyl acetate (500 ml) and was crystallized by the addition of hexanes (1.5 L) to yield ethyl 6-chloro-7-(4-(4-chloro-2-methoxyphenethylcarbamoyl)phenoxy)chroman-4-carboxylate (51.1 g, 93.9 mmol).
