58.5% | 21 Example 21 STR48 A procedure is followed by analogy with Example 1. To the aqueous phase remaining after shaking with dichloromethane is added in portions solid sodium hydrogencarbonate with stirring and cooling (maximum 25° C.) until a pH of 5 to 6 is attained. The mixture is then further extracted three times each time with 250 ml of dichloromethane and worked up in accordance with Example 1. In this manner a further 7.6 g of 72.6% pure, according to GC, 2-chloro-3,5-pyridinedicarboxaldehyde are obtained. This increases the overall yield to 58.5% of theory. |
