Reaktionsschritte

A mixture of ethyl 2-(4-(2-methylpyridin-4-yl)phenyl)acetate 26-2 (1.81 g, 7.1 mmol), LiOH (0.17 g, 7.1 mmol) in THF (30 mL), methanol (10 mL) and H2O (10 mL) was stirred at 60° C. for 1 hour. After cooled down to 0° C., the mixture was neutralized with 1 N HCl at 0° C. and then taken to dryness by rotary evaporation to yield 2-(4-(2-methylpyridin-4-yl)phenyl)acetic acid 26-3. The product was used for next step without further purification. MS m/z 228.1 (M+1).
