実験手順

To a solution of THF (50 mL) of 4-benzyloxy-phenylacetic acid (7.0 g) were added hydrazine monohydrate (4.3 g), WSC (6.7 g), HOBt (4.7 g), and triethylamine (3.5 g), which was stirred for 15 hours at room temperature. Water was added to the reaction mixture, and the precipitated solids were filtered off to obtain the titled compound (1.2 g).
