実験手順

This compound was prepared in a manner analogous to that of Example 1, Step D, using 1.4 grams (0.005 mole) of (4-chlorophenyl) (2,3-dihydro-2,2-dimethylbenzofuran-5-yl)ketone, 0.4 mL (0.008 mole) of hydrazine hydrate, and 0.3 mL of acetic acid in 50 mL of ethanol. The yield of (4-chlorophenyl) (2,3-dihydro-2,2-(dimethyl- benzofuran-5-yl) ketone hydrazone was 1.23 grams. The nmr spectrum was consistent with the proposed structure.
