Participants

Reaction Steps

A mixture of 3-[4-(diisopropoxy-phosphoryl)-phenoxy]-5-(1-methyl-1H-imidazol-2-ylsulfanyl)-benzoic acid methyl ester (292 mg, 0.58 mmol), 3 mL of dioxane, 3 mL of water and 1.2 mL of 1 M aqueous NaOH was stirred for 2 h at rt, diluted with water, washed with EtOAc, the aqueous layer pH lowered to 4 with 1 M NaHSO4, the aqueous layer extracted with 4:1 CH2Cl2/MeOH. The organic extract dried (MgSO4) and evaporated to provide 234 mg (82%) of the title compound: 1H NMR (500 MHz, DMSO-d6): δ 1.18 (d, 6H, J=6 Hz), 1.28 (d, 6H, J=6 Hz), 3.64 (s, 3H), 4.55 (m, 2H), 7.03 (t, 1H, J=2 Hz), 7.13 (s, 1H). 7.15 (dd, 2H, J=8, 3 Hz), 7.31 (dd, 1H, J=2, 1 Hz), 7.35 (t, 1H, J=1 Hz), 7.50 (s, 1H), 7.72 (dd, 2H, J=12, 8 Hz); LCMS (m/z): 491.9 [C23H27N2O6PS+H]+.
