Product Description
ALPHA-(4-chlorophenyl)pyridine-2-methanol CAS number is 27652-89-7 which is a key intermediate for the synthesis of BEPOTASTINE BESILATE. The specific process for synthesizing BEPOTASTINE BESILATE is as follows: in a 5L autoclave, under the condition of connecting argon gas,Separately add 400 g of ALPHA-(4-chlorophenyl)pyridine-2-methanol and 3 L of toluene from the feeding port. Then bubbled and degassed by argon gas, continuously bubbling for 30 min; degassing was completed. Under an argon atmosphere, 100 mg of catalyst (R,R)-DIOPRuCl2(R)-Me-BIMAH was added from the feed port, and finally 6 g of potassium t-butoxide was added; after the addition, the feed port was quickly closed. The argon gas was replaced by hydrogen, and the hydrogen gas passage was closed when the hydrogen gas was slowly introduced to 35 atm; finally stirred, the reaction was maintained at 35 ° C; the pressure was lowered after the stirring was started. Observe the change of pressure. After 4 hours, the pressure will not change, and the sample will be sent for nuclear magnetic and HPLC analysis.
