Reaction Conditions:

with hydroxylamine hydrochloride;sodium hydroxide in ethanol;water at 0 - 90; for 4 h;

Steps:

3.1 (1) Preparation of 2,6-difluorobenzaldehyde oxime

2,6-Difluorobenzaldehyde (10 g, 70.4 mmol) was dissolved in ethanol (100 mL),and a solution ofhydroxylamine hydrochloride (7.3 g,105.0 mmol) and NaOH (4.2g,105.0 mmol) in water (30 mL) wasadded at 0 ° C.The mixture was reacted at 90 ° C for 4 hours, cooled, concentrated to give alarge white solid, filtered, and filtered to give product (11 g, yield: 99.1%).
