Reaction Steps

To a −78° C. solution of 4-bromo-3,6-dimethyl-2-(2,4,6-trimethyl-phenoxy)-pyridine in dry THF was added nBuLi and stirred at that temperature for 20 minutes. Excess propionaldehyde was added and stirred for 2 hours at −78° c. The mixture was quenched with water, extracted with ethyl acetate. The organic layer was washed with brine, dried and concentrated. After column chromatography, an off-white solid was obtained, mp. 119-120° C. 1H NMR(CDCl3) d 6.86(s,3H), 4.90(m,1H), 2.281(s,3H), 2.28(s,3H), 2.21(s,3H), 2.02(s,6H), 1.65-1.8(m,2H), 1.00(t,3H) ppm.
