The title compound was prepared by a method analogous to that described for Intermediate (16), using methyl 4-iodo-3-methylbenzoate and butyraldehyde. 1H NMR (400 MHz, CDCl3, δ): 7.87 (d, J=8.4 Hz, 1H), 7.81 (s, 1H), 7.56 (d, J=8.4 Hz, 1H), 4.98 (q, J=4.4 Hz, 1H), 3.90 (s, 3H), 2.37 (s, 3H), 1.63-1.72 (m, 2H), 1.50-1.54 (m, 1H), 1.39-1.43 (m, 1H), 0.98 (t, J=7.6 Hz, 3H).
