Reaction Steps
To a solution of 50 g of 2-fluoro-3-nitrotoluene in 1.1 L of DMSO are added at room temperature 59.5 g of para-anisidine (1.5 equivalents). After 5 minutes of stirring at room temperature, 57.9 g of potassium tert-butanoate (1.6 equivalents) are added to the reaction medium and the whole is heated to 110° C. for 1 hour. The reaction medium is directly hydrolyzed by adding 1 L of ice and water and then the aqueous phase is extracted several times with ethyl acetate. The organic phases are collected, dried on sodium sulphate, filtered and then dry concentrated. The raw product is chromatographed on silica gel (ether/cyclohexane:0/100, 5/95 and then 20/80) in order to provide 34.95 g of the expected compound as a dark red solid.
