Procedure

Phloroglucinol was treated with prenylchloride using the same procedure as described in Example 2 to yield prenylphloroglucinol. Prenylphloroglucinol was treated with butyrylchloride, according to the same procedure as described for the preparation of 2,4-dibutyrylphloroglucinol in Example 34 (Method 2) to yield 5,7-dihydroxy-6,8-dibutyryl-2,2-dimethylchroman (36) after chromatography with silica gel (petroleum ether, ethyl acetate, 4:1).
