実験手順

A mixture of 1-(5-amino-2-(2-(tert-butyldimethylsilyl)oxyethoxy)-4-fluorophenyl)-4-methyl-1H-tetrazol-5(4H)-one (200 mg), (7R,8aS)—N-(2-chloro-5-cyanopyrimidin-4-yl)-octahydro-5,5-dimethylindolizin-7-amine (120 mg), and benzenesulfonic acid (120 mg) in IPA (2 mL) was heated to 80° C. overnight. After cooling to ambient temperature, the crude mixture was concentrated to dryness. The crude product was absorbed onto silica gel and purified by CombiFlash chromatography (2N NH3 in MeOH/CH2Cl2=0-20%) to give desired product with benzenesulfonic acid. The methanol solution of the salt was passed through an ion-exchange resin column to remove acid to give the free base of compound 78 (120 mg, 57%).
