実験手順

To a stirred solution of 1-benzyloxy-2-methoxy-4-(2-methoxyvinyl)benzene (11.0 g), 4-hydrazinopyridine hydrochloride (6.6 g), and ethanol (150 ml) was added p-toluene sulfonic acid (0.39 g). The reaction mixture was stirred under reflux for 2 hrs and concentrated in vacuo. Recrystallization of the residue from methanol/ether gave 9.48 g (61%) of product, mp 154-155° C.
