Procedure

This compound was obtained by using the same procedure as that described in Example 8(b), by treating 9 g of 1,8-dihydroxy-10-cyclohexylcarbonylanthrone with 150 cm3 of acetic anhydride. After 3 hours the mixture was concentrated, and the oil obtained crystallized out by agitation in hexane. After the solvents had been sucked off, the 11 g of product obtained was dissolved in 150 cm3 of toluene heated to 100° C. and stirred in the presence of 10 g of silica gel. After a few minutes, the solution was filtered and the filtrate was cooled to 0° C. In this way 6 g of light-beige crystals of 1,8-diacetoxy-10-cyclohexylcarbonylanthrone having a melting point of 188° C. was obtained.
