Reaction Steps
A similar procedure to Reference Example 5 was performed by using 6-cyano-3,4-epoxy-3,4-dihydro-2,2-dimethyl-2H-1-benzopyran and methylcarbazate, and as a result, trans-6-cyano-3,4-dihydro-2,2-dimethyl-4-(2-methoxycarbonylhydrazino)-2H-1-benzopyran-3-ol was obtained, m.p. 174°-175° C. (recrystallized from hexane-ethyl acetate).
