2-Bromo-5-formyl-3-methylpyridine Use and Manufacturing
Method 4; Preparation of 6-bromo-5-methylnicotinaldehyde; 2, 5-Dibromo-3-picoline (5.1 g, 20.30 mmol) in tetrahydrofuran (25 ml) was added dropwise to a 2M solution of isopropylmagnesium chloride (10.7 ml, 21.3 mmol) in tetrahydrofuran at 0° C. The solution was stirred for 2 hours at 0° C. and then for 1 hour at ambient temperature. A solution of 4-formylmorpholine (2.1 ml, 20.3 mmol) in tetrahydrofuran (25 ml) was added dropwise and the solution stirred at ambient temperature for 1 hour. The solution was poured into water and extracted with ethyl acetate. The combined organic extracts were washed with brine, dried over magnesium sulphate, filtered and the solution concentrated under reduced pressure. The residue was purified by flash chromatography, eluting with 10percent ethyl acetate in isohexane, to give the title compound (3.0 g, 74percent); NMR Spectrum: (DMSO-dMethod 3; Preparation of 6-bromo-5-methvmicotmaldehvde; 2, 5-Dibromo-3-picoline (5.1 g, 20.30 mmol) in tetrahydrofuran (25 ml) was added dropwise to a 2M solution of isopropylmagnesium chloride (10.7 ml, 21.3 mmol) in tetrahydrofuran at 0
