反応手順

A mixture of 4-(6-cyano-4-(methoxycarbonyl)chroman-7-yloxy)benzoic acid (Preparation 2) (0.041 g, 0.116 mmol), 1-(3-(dimethylamino)propyl)-3-ethyl-carbodiimide hydrochloride (0.0245 g, 0.128 mmol), 1-hydroxybenzotriazole monohydrate (0.0195 g, 0.128 mmol), and 1,2-dichloroethane (1 ml) was stirred at room temp for 0.5 hours. A mixture of 2-(4-chlorophenyl)cyclopropanamine hydrochloride (0.0261 g, 0.128 mmol) and triethylamine (0.0809 ml, 0.580 mmol) in 1,2-dichloroethane (1 ml) was added to the activated acid mixture. The mixture was stirred at ambient temperature for 1 hour. The crude mixture was directly purified on silica gel (EtOAc in hexanes gradient) to provide 50.7 mg of the title compound as a thin film (87%).
