Participants

Reaction Steps

A DMF (4 mL) solution of 4-[[N-(9-fluorenylmethyloxycarbonyl)glycyl]aminomethyl]-1-(4-methylthiobenzyl)piperidine (590 mg) and piperidine (1 mL) was stirred at 60° C. for 2 hours. After concentrating, the obtained crude product was purified by column chromatography (SiO2,triethylamine/methanol/dichloromethane=1:1:9) to thereby afford 4-[(glycylamino)methyl]-1-(4-methylthiobenzyl)piperidine (365 mg) as a white solid. 1H NMR (CDCl3, 270 MHz) δ 1.25 (dd, J=12 Hz, 4.1 Hz, 2H), 1.34 (dd, J=12 Hz, 4.1 Hz, 2H), 1.51 (br-s, 2H), 1.66 (d, J=12 Hz, 2H), 1.77 (d, J=7.3 Hz, 1H), 1.94 (t, J=9.5 Hz, 2H), 2.48 (s, 3H), 2.80 (d, J=12 Hz, 2H), 3.18 (t, J=6.2 Hz, 2H), 3.35 (s, 2H), 3.45 (s, 2H), 7.18-7.29 (m, 4H), 7.35 (br-s, 1H).
