Uses

2,3-Difluorophenylacetic acid may be used in chemical synthesis.

Synthesis

1036273-31-0

145689-41-4

Example 19: Synthesis of 2-(2,3-difluorophenyl)acetic acid Using methyl 2,3-difluorophenylacetate (CAS: 1036273-31-0) as a raw material, the following was performed: 1. 10 mL of water and 0.8 mL of 30% sodium hydroxide solution were added to 0.3 g of methyl 2,3-difluorophenylacetate. 2. the reaction mixture was stirred at 60 °C for 1 h until the reaction was complete. 3. After completion of the reaction, the mixture was acidified to pH=1 with concentrated hydrochloric acid. 4. The product was separated by filtration to afford 2-(2,3-difluorophenyl)acetic acid as a white solid in a yield of 0.2 g (72% yield). Product Characterization: 1H-NMR (300 MHz, CDCl3): δ (ppm): 3.75 (s, 2H); 7.01-7.06 (m, 3H); 9.4 (bs, 1H).
