A stirrd mixture of triethyl phosphite (0.500 g, 2.95 mmol) and 3-cyanobenzyl bromide (0.609 g, 2.95 mmol) was refluxed at 140° C. under argon for 2 h and the resulting volatiles were removed at room temperature in vacuo to afford the tided intermediate as a colorless oil (0.62 g, 84%). 1H-NMR (400 MHz, CDCl3) δ 7.7-7.5 (m, 3H), 7.44 (t, J=7.8 Hz, 1H), 4.06 (p, J=7.6 Hz, 4H), 3.17 (d J=21.8 Hz, 2H), 1.27 (t, J=7.1 Hz, 6H).
