2,3,4-Trifluorobenzaldehyde Use and Manufacturing

Compound 4 (1140 g, 3 mol) and anhydrous THF (7.5 L) were added to a 30 L reaction flask and stirred. Compound 5 (566 g, 3.45 mol), compound 6 (502 g, 1.1 mol) and N-methylmorpholine (760 g, 7.5 mol) were added. The reaction solution was refluxed (60 C.) for 20 hours, cooled to 5 C. to 10 C., added with isobutyl chloroformate (492 g, 3.6 mol, dissolved in 500 mL THF) dropwise, and reacted at 5 C. to 10 C. for 1 hour. After the intermediate carboxylic acid was completely reacted, the reaction was quenched by the addition of water (3 L). Ethyl acetate (9 L) was added for extraction and the organic phase was washed with water (3 L) once, concentrated to give a mother liquor of 2.2 kg. The mother liquid was dissolved in ethyl acetate (3 L), added with tetrahydrofuran (500 mL), slowly added dropwise within-heptane (about 9 L), and stirred at 15 C. overnight to precipitate a solid. The solid was recrystallized from tetrahydrofuran/ethyl acetate/n-heptane solvent system (5 mL/5 mL/10 mL/g) to obtain 500 g compound 8A, of which the purity reached 96%, ee value>96% and yield was 27.1%.
