Versuchsvorschrift

To a stirred solution of the hydrochloride (0.33 g, 0.92 mmol) obtained in Step II, in DMSO (3.7 mL) at room temperature under nitrogen atmosphere (2S)-1-(chloroacetyl)pyrrolidine-2-carbonitrile (0.16 g, 0.92 mmol) and K2CO3 (0.76 g, 5.53 mmol) were added. After stirring the reaction mixture for 3 h, 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-[(4-methylpiperazin-1-yl) methyl]hexahydro-2,5-methanopentalen-3a (1H)-yl]glycyl}pyrrolidine-2-carbonitrile as an off-white solid (0.12 g) in 47% yield. m/z (M+1) 386; 1H NMR (CDCl3+CD3OD) 300 MHz δ 4.78 (d, J=5.7 Hz, 1H), 3.85-3.50 (m, 4H), 3.30-3.10 (m, 5H), 2.85-2.70 (m, 8H), 2.52-2.45 (m, 2H), 2.38-2.20 (m, 4H), 2.10-1.90 (m, 4H), 1.70-1.40 (m, 5H), 1.40-1.27 (m, 1H).
