Here is a downstream synthesis route of the compound, 7295-76-3, blongs to pyridine-derivatives compound. COA of Formula: C6H7NO

General procedure: [Li(TMP)Zn(tBu)2] 1 was made according to the literature procedure2 on a 0.4 mmol scale in THF solution. To this solution 3-methoxypyridine (0.042 mL, 0.4 mmol) was added and the resultant light orange reaction allowed to stir at room temperature for 2 hours. This solution was then transferred to a THF (1 mL) solution of PdCl2(dppf) (29.3 mg, 10 mol %) and 1-bromo-4-chlorobenzene (76.6 mg, 0.4 mmol) to give a heterogeneous red solution. The reaction mixture was then reacted in the microwave at 100C for 10 minutes. The reaction was then quenched with saturated NH4Cl solution (2 mL) and extracted with DCM (3 x 1 mL). The organic fractions were combined and dried by passing through a phase separator cartridge with a hydrophobic frit and the solvent removed under reduced pressure. The residue was purified by column chromatography using a 4 g C18 silica cartridge and eluent Acetonitrile + 0.1 % formic acid:H2O + 0.1 % formic acid (5:95 to 95:5) to give compound 3b as an off white solid 26.5 mg (30% yield) 1H NMR (400 MHz, CDCl3) delta ppm 3.93 (s, 3H) 7.24 (d, J=4.69 Hz, 1 H) 7.39 – 7.46 (m, 2 H) 7.48 – 7.56 (m, 2 H) 8.33 (d, J=4.49 Hz, 1 H) 8.39 (s, 1 H).

General procedure: First, 10 mmol of the respective pyridine were dissolved in 50 mL of dried THF. After additionof 0.5 mmol of copper(I) iodide and 3 mL of dimethyl sulphide, the mixture was stirred at room temperature until a clear solution resulted. Then, it was cooled down to -20 C. After 15 min, 10 mmolof acetyl chloride were added dropwise and stirring continued for 15 min. Then, 10 mmol of phenylmagnesium chloride were added and stirring followed for additional 15 min. Then, the mixturewarmed up to room temperature. Then, 50 mL of an ammonium chloride solution (20%) were addedand extraction with diethyl ether followed with portions of 50, 25 and again 25 mL. The unified organiclayer was extracted with each 50 mL of a solution of ammonium chloride in ammonia for two times,with 50 mL water, hydrochloric acid (10%) for two times, water and finally a saturated solution ofsodium chloride in water. The organic layer was then dried over sodium sulphate, filtered and finallyremoved under reduced pressure to give an oily substance that partially crystallized from methanol.
