実験手順
A mixture of compound D3 (355 mg, 0.500 mmol), cyclopropyl-(2,3-dichlorobenzyl)-amine (prepared from 2,3-dichlorobenzaldehyde and cyclopropylamine by reductive amination, 324 mg, 1.50 mmol), DIPEA (0.342 mL, 2.00 mmol), DMAP (15.3 mg, 0.125 mmol), HOBt (101 mg, 0.75 mmol) and EDC.HCl (288 mg, 1.50 mmol) in CH2Cl2 (7 mL) was stirred at rt for 2 weeks. The mixture was diluted with more CH2Cl2, and washed with aq. 1M HCl (3×) and aq. sat. NaHCO3 (1×). The org. extracts were dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Purification of the residue by FC (EtOAc/heptane 1:9→2:8 3:7→4:6→1:1) yielded the title compound (160 mg, 35%). LC-MS: tR=1.34 min, ES+: 909.35.
