Reaction Conditions

Reaction Steps

12 g of 2-hydroxybenzaldehyde was placed in a 500 ml round bottom flask with 100 ml of diallyl amine and 100 ml of methanol. The reaction mixture was then cooled to 0° C. 4 g of NaBH4 (powder) was slowly added within 2.5 hrs and the temperature was kept at 0-6° C. Water was then added to the reaction mixture to terminate the reaction. The reaction mixture was then concentrated, and extracted with ethyl acetate and water. The organic phase was collected and concentrated to obtain crude product. The obtained crude product was eluted and purified with mobile phase eluant of n-hexane:ethylacetate (EA)=4: 1 and solid phase of silica gel. 12.8 g of the product of formula (IX) was obtained and recovery yield was 64%.
