实验过程

2-(N-ethyl-N-phenylamino)ethanol (10 g, 60 mmol) in CH2Cl2 (150 mL) was reacted with SOCl2 (8.8 mL, 121 mmol). The mixture was heated to reflux for one hour and quenched. The solvent was evaporated and the residue was purified by silica gel column chromatography to provide intermediate 3a (5.54 g, 30 mmol, 50%) as a yellow oil. 1H NMR (CDCl3, 400 MHz) δ 7.28 (m, 2H), 6.74 (m, 3H), 3.65 (m, 4H), 3.46 (q, J=7.2 Hz, 2H), 1.22 (t, J=7.2 Hz, 3H); HRMS (ESI, positive) m/z calcd. for C10H15ClN [M+H]+: 184.0893, found: 184.0836.
