YieldReaction ConditionsOperation in experiment
With potassium hydroxide; at 20 - 55℃; for 1.33333h; Flaked potassium hydroxide (59.575g) was added portionwise to stirred and cooled (ice-bath) methanol (600ml_) keeping the temperature below 20C. This solution was transferred to a dropping funnel. The starting material, 4-bromo-2,6-difluoro-benzaldehyde (commercially available, Chemical Abstracts Reg. No. 537013-51 -7, 200g), was dissolved in methanol (1210ml_) at 25C. The mixture was warmed to 40C and the potassium methoxide solution added from the dropping funnel over 20 minutes with stirring. An initial exotherm was observed which was controlled by external cooling. The reaction temperature was increased to 55C and heating was continued for 1 hour. The reaction mixture was cooled to room temperature and the methanol was removed under vacuum. The resultant residue was partitioned between water (1.6L) and ethyl acetate (1 .6L). The phases were separated and the aqueous layer extracted with further ethyl acetate (2 x 0.5L). The combined organic phases were washed with water (0.5L) and concentrated under vacuum leaving a yellow solid. This solid was triturated with cold iso-hexane, filtered and dried in vacuo to give a yellow solid as a 4:1 mixture of the desired compound 4-bromo-2-fluoro-6-methoxy- benzaldehyde [1 H-NMR (400 MHz, CDCI3) 10.36 delta (delta): (s, 1 H), 6.94-6.97 (m, 2H), 3.94 (s, 3H)] and 4-bromo-2,6-dimethoxy-benzaldehyde
