Participants

Reaction Steps

To a solution of 4-(1-ethyl-propoxy)-6-methyl-2-(2,4-dichloro-phenylamino)-nicotinic acid in dry THF was added BH3.DMS. The resulting mixture was heated at reflux overnight. The mixture was quenched with dilute HCl and stirred for 30 min, adjusted pH to 7.5-8.5, then extracted with ethyl acetate. The organic layer was separated, dried and concentrated to give a golden oil. After silica gel column chromatography, the title compound was obtained as a golden oil. 1H NMR(CDCl3) d 8.44(d,1H), 8.18(s,1H), 7.32(d,1H), 7.179d,1H), 6.28(s,1H), 4.82(s,2H), 4.21(m,1H), 2.42(s,3H), 1.6-1.8(m,4H), 0.94(t,6H) ppm.
