Reaction Steps
(2R)-1-[(1R)-(Cyclopropyl)-(2-methylphenyl)methoxy]-3-[[2-methyl-1-(naphthalen-2-yl)propan-2-yl]amino]propan-2-ol (1.25g) was dissolved in chloroform (10 ml) and, under ice-cooling, pyridine (0.485 ml) and maleic anhydride (294 mg) were added and the mixture was stirred for 4 hr. The reaction mixture was concentrated under reduced pressure, and diethyl ether was added to the obtained residue. The organic layer was washed successively with water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (chloroform:methanol=98:2-95:5) to give the title compound (1.40 g).
