Procedure

About 7 gm of isobutylene were introduced into a refluxing solution of 11.3 gm of 1,8-dihydroxy-9-(10H)anthracenone in 100 ml of chloroform and 6 ml of sulfuric acid. The resulting mixture was poured into water, and the organic phase was separated and worked up as described in Example 2. 3.9 gm of 2-tert. butyl-1,8-dihydroxy-9-(10H)anthracenone, m.p. 126°-127° C., corresponding to 27% of theory, were obtained.
