実験手順
i. 2,7-Dimethyl-benzofuran. 7-Methyl-benzofuran (cf. compound (2) g.) is subjected to a WILSMEYER reaction to form 7-methyl-benzofuran-2-aldehyde which is converted into 2,7-dimethyl-benzofuran by a WOLFF-KISHNER reaction by the method described in Bull.Soc.Chim.France 29, 1875 (1952). The product thus obtained has the following peaks in its MS: 146 (100%), 145 (92%) and 131 (32%).
