실험 절차

A solution of 1.4 g. of 4-amino-3,5-dimethoxybenzaldehyde in 20 ml. of 50% hydrogen tetrafluoroborate was diazotized at 0° C. with a solution of 0.59 g. of sodium nitrite in about 2 ml. of water. After irradiation with a low pressure mercury lamp (Hanau NK 6620) for 6 hours at room temperature, the solution was extracted with ether, the ether extracts dried over magnesium sulfate and concentrated. After recrystallization from heptane, the residue produced 3,5-dimethoxy-4-fluoro-benzaldehyde of melting point 97°-98° C.
