실험 절차

To a stirred mixture of the compound obtained from step II (0.2 g, 0.94 mmol) and K2CO3 (0.39 g, 2.8 mmol) in DMSO (4.0 mL) at ice bath temperature under nitrogen atmosphere (S)-1-(2-chloro-acetyl)pyrrolidine-2-carbonitrile (0.16 g, 0.94 mmol) was added. After stirring the reaction mixture for 3 h at r.t., it was diluted with EtOAc and washed with water and brine, dried over Na2SO4, and the solvent was removed under reduced pressure. The crude product was purified by column chromatography to obtain (2S)-1-[N-(2-phenylhexahydro-2,5-methanopentalen-3a(1H)-yl)glycyl]pyrrolidine-2-carbonitrile as off-white solid (0.16 g) in 48% yield. m/z (M+1) 350; 1H NMR (CDCl3) 300 MHz δ 7.35-7.16 (m, 5H), 4.4.85-4.76 (m, 1H), 3.76-3.40 (m, 2H), 3.50 (s, 2H), 2.48-2.41 (m, 1H), 2.36-2.27 (m, 2H), 2.23-2.0 (m, 6H), 1.94-1.68 (m, 4H), 1.66-1.60 (m, 1H).
