Sodium Hydroxide → HCID 59385441, compound

Participants

Reaction Steps

Methyl 2-[(3,5-difluorophenyl)acetylamino]-2-methoxyacetate 2A (0.4 g) was dissolved in 10 mL of dioxane and treated with 2.8 mL of a 1.0 N aqueous sodium hydroxide solution. After 1.5 h most of the solvent was removed by evaporation at reduced pressure. The mixture was acidified with an aqueous solution of sodium bisulfate and washed with two successive portions of ether. The combined organic extracts were washed with brine and then dried with magnesium sulfate. The solution was filtered and the solvent was evaporated at reduced pressure to yield 2-[(3,5-Difluorophenyl)acetylamino]-2-methoxyacetic acid 3 as 0.35 g of a white powder. 1H-NMR (DMSO-d6): δ 9.06 (d, J=8.7 Hz, 1H), 7.15-6.85 (m, 3H), 5.23 (d, J=8.7 Hz, 1H), 3.57 (s, 3H), 3.21 (s, 2H).
