Participants

Reaction Steps

Combined 2-(2,5-Dichloro-pyrimidin-4-ylamino)-3-fluoro-N-methyl-benzamide (77 mg, 0.244 mmol), 7-Amino-1-ethyl-5,5-dimethyl-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (60 mg, 0.258 mmol), DL-10-Camphorsulfonic acid (70 mg, 0.301 mmol) and isopropanol (4 mL) in a microwave tube. Microwaved reaction at 120° C. for 30 minutes. Evaporated off solvent, dissolved residue in methylene chloride and washed with saturated sodium bicarbonate solution, then brine. Dried with magnesium sulfate, filtered and purified with normal phase chromatography eluting with hexane/ethyl acetate to yield a yellow solid, 2-[5-Chloro-2-(1-ethyl-5,5-dimethyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamino)-pyrimidin-4-ylamino]-3-fluoro-N-methyl-benzamide (70 mg, 56%).
