Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 716362-10-6, name is 6-Chloro-4-methoxynicotinic acid. This compound has unique chemical properties. The synthetic route is as follows.

Synthesis of 6-chloro-N,4-dimethoxy-N-methylnicotinamide (3) (0673) To a solution of 6-chloro-4-methoxynicotinic acid (1, 25.0 g, 133.6 mmol) in dichloromethane (300 mL), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (38.44 g, 200.5 mmol), 1-hydroxybenzotriazole (30.40 g, 200.4 mmol) and N,N-diisopropylethylamine (69.8 mL, 400.8 mmol) were added at 0 C. and stirred the mixture for 5 min. N, O-dimethylhydroxylamine hydrochloride (2, 19.56 g, 200.53 mmol) was then added at same temperature and the reaction was stirred for 16 h at room temperature. After completion, reaction mass was diluted with dichloromethane and washed with cold water. The organic layer was separated and dried over sodium sulphate, filtered and concentrated to give crude. The crude was re-crystallised in ethanol to afford 6-chloro-N,4-dimethoxy-N-methylnicotinamide (3) as white solid. Yield: 19.3 g, 62%; MS (ESI) m/z 231.17 [M+1]+.
