Versuchsvorschrift

4-Chloro-2-Fluorobenzaldehyde (300 mg, 1.89 mmol) was diluted with NaOMe (3784 μL, 1.89 mmol) (solution in methanol), heated to 50° C. and stirred for 3 hours. The reaction was concentrated in half and loaded directly onto a biotage 25 cartridge eluting with 5% ethyl acetate/hexanes to yield 4-chloro-2-methoxybenzaldehyde (250 mg, 1.47 mmol, 77.5% yield).
