A mixture of N-{[3-(dibenzylamino)tetrahydrofuran-3-yl]methyl}-2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)-6-methylquinolin-4-amine (270 mg, 0.43 mmol), 10% palladium hydroxide on active carbon (300 mg) in methanol (20 mL) was stirred for 16 hours at room temperature under hydrogen atmosphere (1 bar). The resulting mixture was concentrated in vacuo. The residue was purified by preparative HPLC to afford 21 mg of the desired product (yield was 10.8%). MS obsd.
