Reaction Steps

To a solution of [2-(4-bromo-2,6-dimethyl-phenoxy)-3,6-dimethyl-pyridin-4-yl]-(1-ethyl-propyl)-amine in dry THF was added n-butylithium at −78° C. After stirring at −78° C. for 10 min, n,N-dimethylformamide was added and the resulting mixture was stirred at −78° C. for 20 min, the dry-ice bath was removed. After stirring for 5 min, the mixture was quenched with diluted HCl, water and adjusted to pH 7.5 and extracted with ethyl acetate. The organic layer was separated, dried, and concentrated to dryness. The residue was purified through silica gel chromatography to give the title compound. 1H NMR(CDCl3) d 9.93(s, 1H), 7.60(s, 2H), 6.10(s, 1H), 3.75(d, 1H), 3.35(m 1H), 2.17(s, 6H), 2.13(s, 3H), 2.12(s, 3H), 1.4-1.8(m, 4H), 0.97(t, 6H) ppm.
