Reaction Conditions:
with sulfuric acid in toluene at 100; for 1 h;
Steps:
5
In a 1000 mL reaction flask,Followed by 2-chloro3- {2-chloro-5- [4- (difluoromethyl) -4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol- ] -4-fluorophenyl} propionic acid (100 g),Concentrated sulfuric acid (5g),Toluene (400 mL),Add absolute ethanol (50g),After heating, the reaction was continued at 100 ° C for 1 hour.The residue was washed with activated carbon (5 g) and the filtrate was washed with water (200 mL)5% sodium bicarbonate solution (2 x 200 mL),0.5% dilute hydrochloric acid (200 mL),And water (200 mL).The viscous liquid product (98 g) was evaporated at atmospheric pressure.
