YieldReaction ConditionsOperation in experiment
In butanone; at 115 - 117℃; for 3h;Reflux;Product distribution / selectivity; Example 4: l-benzyl-4-[(5,6-dimethoxy-l-indanone-2-yl)methylene]pyridinium bromide of formula VTo a round bottom flask equipped with mechanical stirrer, thermometer pocket, addition funnel and condenser, charged methyl isobutyl ketone (1200ml) and 5,6- dimethoxy-2-(4-pyridylmethylene)-l -indanone (lOOg). The reaction mixture was then refluxed at a temperature of 115C to 117C. To the refluxing reaction mixture then added benzyl bromide (75.5g) dropwise over a period of 30 minutes. The reaction mixture stirred further for 2.5 hours. Cooled the reaction mixture at a temperature of 25C to 28C to obtain the product, l-benzyl-4-[(5,6-dimethoxy-l-indanone-2- yl)methylene]pyridinium bromide. Filter the product obtained and washed with methyl isobutyl ketone. Dry the product under vacuum at a temperature of 50C to 55C for 1-2 hours.Yield: 98.76% Purity: 97.5%
