Reaction Steps
A 1 L reactor was charged with 171 g of 4-hydroxybenzaldehyde, 46.6 g boron oxide, 300 g N,N-dimethylacetamide, 70.2 g 2,4-pentanedione and 145.5 g triethyl borate. The mixture was stirred and heated to a temperature of 80° C. under nitrogen. n-Butylamine totaling 21.3 g was then fed dropwise into the reaction mixture over a period of 60 minutes. The temperature of the reaction mixture varied between 80° and 85° C. during this period.
