Procedure

A solution of 156 mg (0.335 mmole) dl-5-acetoxy-4-(4-acetylamino-2-butyl)-2-methyl-7-(5-phenyl-2-pentyl)-3,4-dihydro-2H-benzopyran and 46 mg (0.333 mmole) potassium carbonate in 40 ml of methanol is stirred at room temperature for two hours. After neutralization with acetic acid the mixture is evaporated in vacuo and the residue taken up in ethyl ether. The ether solution is washed successively with water, saturated sodium bicarbonate, brine and dried over magnesium sulfate. Evaporation of ether affords the title amide.
