Participants

Reaction Steps

A solution of 3-[6-(3-chloro-4-fluorophenylamino)-pyrimidin-4-ylamino]phenylamine (IR-4) (300 mg, 0.9 mmol) and triethylamine (500 mg, 5 mmol) in 10 mL of THF was stirred at RT. 2-Chloroethanesulfonyl chloride (360 mg, 2.25 mmol) was added into the reaction mixture and stirring was continued at RT for 1 hr. The crude product was purified by flash chromatography on silica gel with EtOAc/heptane solvent system to afford 35 mg (9%) of the title compound, a brown colored solid. MS (m/z): MH+=420, 422. 1H NMR (DMSO): 9.92 (s, 1H), 9.29 (s, 1H), 9.21 (s, 1H), 8.26 (s, 1H), 7.92 (m, 1H), 7.40-7.22 (m, 4H), 7.14 (m, 1H), 6.20 (m, 2H), 6.05 (m, 3H) ppm.
