실험 절차

A mixture of N-{[3-(dibenzylamino)oxetan-3-yl]methyl}-2-(1,1-dioxido-8-phenoxy-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)-6-methylquinolin-4-amine (90 mg, 0.13 mmol), palladium hydroxide on carbon (40 mg) and trifluoroacetic acid (0.1 mL) in methanol (30.0 mL) was stirred at room temperature under hydrogen (2 bar) for 14 hours. Then the reaction mixture was filtered and concentrated in vacuo. The residue was purified by preparative HPLC to afford 10.5 mg of the desired product as a white solid (yield was 15.2%). MS obsd.
