Participants

Reaction Steps

In a mixed solvent of concentrated hydrochloric acid (15 ml) and methanol (15 ml), 9-acetamido-2-methoxy-6,11-dihydrodibenz[b,e]oxepin-11-one obtained in Reference Example 10 (0.93 g, 3.1 mmol) was heated under reflux for one hour. After the reaction was completed, substantially the same procedure as in Reference Example 5 was repeated to give 9-amino-2-methoxy-6,11-dihydrodibenz[b,e]oxepin-11-one (yield: 74%).
