Procedure

To a solution of 4-(6-chloro-4-(ethoxycarbonyl)chroman-7-yloxy)benzoic acid (0.0899 g, 0.238 mmol), N,N-dimethylpyridin-4-amine (0.00291 g, 0.0238 mmol), and (1R,4R)-4-phenylcyclohexanamine (0.0627 g, 0.358 mmol) in DMF (1.25 ml) was added N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.0549 g, 0.286 mmol), and the reaction was stirred overnight. The reaction was diluted with EtOAc and washed with 1M hydrochloric acid, saturated sodium bicarbonate, and saturated sodium chloride. The organic layer was separated and dried over anhydrous sodium sulfate, filtered, and concentrated. The crude material was purified on a Biotage SP1 system eluting with a linear gradient of 5% to 50% EtOAc in hexanes to yield two isomers of the product. The first eluting isomer was collected and called isomer 1 (27 mg). The second eluting isomer was called isomer 2 (32 mg). The relative configurations of each of these isomers were not determined.
