Reaction Steps

To a mixture of 2-acetamido-5-bromopyridine (240 mg), tri-n-butylamine (456 mg), palladium(II) acetate (0.13 mg) and triphenylphosphine (1.5 mg) in xylene (0.48 ml) was dropwise added acrylic acid (97 mg) at 150° C., and the mixture was stirred for 7 hours at the same temperature. After cooling the mixture, water was added thereto, and the mixture was adjusted to pH4 with hydrochloric acid. The precipitate was collected by filtration, washed with xylene and water, and dried to give (E)-3-(6-acetamidopyridin-3-yl)acrylic acid (173 mg) as yellow crystals.
