実験手順

To a solution of N-[3-(benzyloxycarbonylamino)-1-propoxy]phthalimide (1.42 g, 4.0 mmol), as prepared in the preceding step, in ethanol (20 mL) and tetrahydrofuran (20 mL) was added 40% methylamine (2 mL, 25 mmol). The solution was stirred at room temperature for 1 h. The solvent was evaporated and the residue passed through silica gel (3:1 ethyl acetate:hexane to ethyl acetate) to give the title compound as a white solid (870 mg, 97%). 1H-NMR (300 MHz, CDCl3) δ 7.36 (m, 5H), 5.38 (br s, 2H), 5.09 (s, 2H), 5.08 (br s, 1H), 3.37 (t, J=5.9 Hz, 2H), 3.29 (q, J=6.2 Hz, 2H), 1.79 (pentet, J=6.2 Hz, 2H).
