실험 절차
Ethyl [2-(1-cyclohexenyl)-4-oxo-4H-[1]-benzopyran-8-yl]acetate (2.5 g) was dissolved in acetic acid (35 ml) and to the solution was added 50% sulfulic acid (30 ml). The mixture was relfuxed for 4 hours. The reaction mixture was diluted with water and crystals deposited were filtered off and recrystallized from the mixed solvent of ethyl acetate and methanol to obtain the title compound, yield 68%.
