Versuchsvorschrift

To a solution of 3-phenylcyclobutanamine (0.101 g, 0.686 mmol) in DMF (2 ml) was added 4-(6-chloro-4-(ethoxycarbonyl)chroman-7-yloxy)benzoic acid (0.129 g, 0.343 mmol), N,N-dimethylpyridin-4-amine (0.00838 g, 0.0686 mmol), and N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (0.0789 g, 0.412 mmol), and the reaction was stirred for 16 hours at ambient temperature. The reaction was diluted with EtOAc and washed with 1M hydrochloric acid, saturated sodium bicarbonate, and saturated sodium chloride. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated. The crude material was on a Biotage SP1 system eluting with a 5-70% EtOAc in hexanes linear gradient to yield 86 mg of the title compound (49.5% yield).
