Reaction Steps

To a stirred solution of ((1R,4S)-4-(tert-butoxycarbonylamino)cyclopent-2-enyl)methyl 4-methylbenzenesulfonate (step 1, about 0.5 g) in DCM (50 ml), potassium carbonate (about 0.3 g) was added at room temperature and cooled to about 0° C. After ten minutes, 4-benzylpiperidine (0.17 g) was added and stirred the reaction at room temperature for about 6 hours. Completion of the reaction was monitored by TLC. The reaction mixture was neutralized and extracted with DCM, the organic layer was dried over Na2SO4 and concentrated under reduced pressure to furnish the title compound (0.45 g) as light yellow liquid. 1H NMR (300 MHz, CDCl3: 1.24-1.29 (m, 1H); 1.39-1.40 (s, 9H); 2.29-2.60 (m, 7H); 2.79-2.80 (m, 1H); 3.70-3.73 (m, 4H); 4.63 (S, 1H); 5.37-5.39 (d, J=6 Hz, 1H); 5.72-5.81 (m, 2H).
