実験手順

3,8-Diaza-bicyclo[4.2.0]octane-3-carboxylic acid tert-butyl ester (Intermediate 1, 300 mg, 1.42 mmol), biphenyl-2-carbonyl chloride (429 mg, 1.98 mmol) and tri-ethyl amine (0.6 mL, 3.95 mmol) were dissolved into DCM (5 mL) and stirred at room temperature for 18 h. The reaction mixture was diluted with DCM (25 mL) and washed with 1N NaOH (10 mL) and water (2×20 mL). The organic layers were combined, dried, filtered and concentrated under reduced pressure to yield 8-(Biphenyl-2-carbonyl)-3,8-diaza-bicyclo[4.2.0]octane-3-carboxylic acid tert-butyl ester (380 mg, 68.6%). MS (ESI) mass calcd. for C24H28N2O3, 392.49; m/z found, 293.2 [M+H]+ (mass without Boc group). 1H NMR (CDCl3): 7.57-7.30 (m, 9H), 4.60-4.35 (m, 0.5H), 4.17-3.98 (m, 0.5H), 3.90-3.71 (m, 1H), 3.60-3.25 (m, 3H), 3.22-2.66 (m, 2H), 2.54-2.38 (m, 0.5H), 2.37-2.22 (m, 0.5H), 2.10-1.92 (m, 0.5H), 1.85-1.56 (m, 1.5H), 1.55-1.27 (m, 9H).
