Reaction Steps
5-Hydroxy-4-methoxy-2,6,6-trimethyl-2-cyclohepten-1-one (AU154) obtained in Example 4 (25.0 g, 126 mM) was treated with 3,4-dinitrobenzoic acid according to the procedures described in Example 20, and crystallized from methanol to obtain 42.1 g (85%) of 5-(3,4-dinitrobenzoyloxy)-4-methoxy-2,6,6-trimethyl-2-cyclohepten-1-one (AU409) as light yellow needles. Melting point: 103° to 104° C.
