Procedure

A solution containing 2.68 g of 3-phenyl-2-propanone and 3.66 g of 3,4-dihydroxy-5-nitrobenzaldehyde in 80 ml of 2-propanol was saturated with hydrogen chloride gas at 20° C. The mixture was stirred for 4 h at room temperature, filtered and washed with 2-propanol. The product was recrystallized from methanol. Yield 1.34 g, mp 170°-176° C.
