Reaction Steps
88 g of salicylaldehyde were dissolved in 300 ml of anhydrous ethyl acetate together with 132 g of omega-acetoxyacethophenone. The solution was cooled to 0° C. and saturation with gaseous HCl commenced, which took about one hour. The mixture was then left at 4° C. for 48 hours and the crystallised solid filtered off, this consisting of 106 g of 3-hydroxyflavylium chloride.
