The title compound was prepared according to the procedure for Compound 113A using bis(2,2,2-trifluoroethyl)(3-methoxy-4-nitrobenzyl)phosphonate (Compound 114B, 2.8 g, 6.81 mmol). The reaction mixture was filtered and the filtrate was concentrated to give the desired product (2 g, 77%). 1H NMR (DMSO-d6, 400 MHz): δ=3.29 (d, J=21.2 Hz, 2H), 3.68 (s, 3H), 4.50-4.61 (m, 4H), 4.64 (s, br, 2H), 6.50-6.60 (m, 2H), 6.67 (s, 1H).
