Following a procedure analogous to that for the synthesis of Example 106, 3,4-dichloroaniline (1.62 g, 10.0 mmol) and butyraldehyde (721 mg, 10.0 mmol) were converted to the title compound (1.24 g, 57%). 1H NMR (CDCl3) δ 7.17 (d, J=8.8 Hz, 1H), 6.65 (d, J=2.9 Hz, 1H), 6.41 (dd, J=2.8, 8.7 Hz, 1H), 3.05 (t, J=7.0 Hz, 2H), 1.65-1.53 (m, 2H), 1.43 (qd, J=7.3, 15.0 Hz, 2H), 0.98 (t, J=7.4 Hz, 3H); MS(ESI+) m/z 218.1 (M+H)+.
