実験手順

A mixture of (1R,6S)-8-(4,6-dimethyl-pyrimidin-2-yl)-3,8-diaza-bicyclo[4.2.0]octane (60 mg, 0.28 mmol), 5-methyl-2-pyrimidin-2-yl-benzoic acid (61.82 mg, 0.29 mmol), HOAT (56.12 mg, 0.41 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide HCl (79.1 mg, 0.41 mmol), TEA (83.5 mg, 0.83 mmol) was taken into DMF (5 mL) and stirred at 50° C. for 4 h. The reaction mixture was cooled and diluted with ethyl acetate (50 mL). It was washed with sat. aqueous NaHCO3 solution (2×25 mL) and with water (2×60 mL). The ethyl acetate layer was dried over Na2SO4, filtered and concentrated. The crude product was purified three times on Agilent Basic HPLC system to yield the title compound (24 mg, 21%). MS (ESI) mass calcd. for C24H26N6O, 414.51; m/z found 415.2 [M+H]+. 1H NMR (400 MHz, CDCl3): 9.17-5.47 (m, 7H), 4.89-1.08 (m, 19H).
