Reaction Steps

A solution of 2-(4-carbamoyl-3-fluorophenylamino)-2-methylpropanoic acid and K2CO3 (1.5 equivalents) in DMF (10 fold) was stirred at RT for 10 min. MeI (1.5 equivalents) was added and the reaction mixture was heated at 55-60° C. for 2 h. The solvent was removed under reduced pressure and the reaction mixture was poured in water, extracted with ethyl acetate (100 mL×2), dried over Na2SO4, concentrated and purified by column chromatography. 1H NMR (CDCl3, Freebase): δ (ppm) 7.9 (t, 1H), 6.5 (bs, 1H), 6.4 (d, 1H), 6.2 (d, 1H), 5.6 (bs, 1H), 4.6 (bs, 1H), 3.75 (s, 3H), 1.6 (s, 6H).
