実験手順

To a solution of a 6:1 mixture of 4-[(2-fluoroethyl)amino]-2-(trifluoromethyl)benzonitrile and 4-[bis(2-fluoroethyl)amino]-2-(trifluoromethyl)benzonitrile (0.100 g) in acetonitrile (3 mL) was added Cs2CO3 (0.169 g, 0.52 mmol) and methyl bromoacetate (0.080 g, 0.52 mmol). The mixture was heated at 85° C. for 2 h. Upon cooling, additional methyl bromoacetate (0.080 g, 0.52 mmol) was added and heated at 85° C. for 8 h. Upon cooling, the mixture was partitioned between ethyl acetate and water. The organic phase was washed with brine, dried (Na2SO4), and concentrated in vacuo. The residue was purified by radial chromatography (10-80% EtOAc-hexanes gradient) to give 0.052 g (50% yield) of the desired product as a white solid: 1H NMR (400 MHz, CDCl3) δ 7.62 (d, J=8.9 Hz, 1H), 6.92 (d, J=2.7 Hz, 1H), 6.76 (dd, J=8.9, 2.7 Hz, 1H), 4.68 (dt, J=47.0, 4.8 Hz, 2H), 4.21 (s, 2H), 3.81 (dt, J=25.6, 4.8 Hz, 2H), 3.78 (s, 3H).
