2-BROMO-6-METHOXY-4-PYRIDINECARBOXYLIC ACID Use and Manufacturing

Step 1 : A solution of sodium methoxide (375 mg) and methyl 2, 6 dibromo- isonicotinate (1 .0 g) in MeOH (20 ml) is heated in a microwave oven at 130C for 30 min. Then additional sodium methoxide (281 mg) is added and heating continued for additional 15 min at 130C. Concentrated sulphuric acid (1 .86 ml) is then added to the reaction mixture and the resulting suspension is heated for 4 h at 80-85C. After cooling to room temperature, the mixture is poured into an ice cold aqueous sodium carbonate solution (100 mL) and extracted withdichloromethane (100 ml). The organic layer is separated, dried over Na2S04 and concentrated in vacuum. The residue is purified by MPLC (dichloromethane: MeOH = 100:3 to 100:5) to yield 710 mg of a 7:3 mixture of 2-bromo-6- methoxyisonicotinate (497 mg) and the corresponding trimethyl citrazinic acid (213 mg). HPLC (Rt) = 1 .66 min (method D). This mixture is then used in a procedure analog to Step 2 in Method 1 .
