Reaction Steps

To a solution of N-{3-[(2-chloro-5-fluoropyrimidin-4-yl)amino]phenyl}prop-2-enamide (0.05 g) and 2-(4-aminophenoxy)ethanol (0.031 g) in 1-butanol (2 mL), was added HCl (0.3 mg). The reaction mixture was heated to reflux for 5 hr. Completion of reaction was monitored by TLC using chloroform:methanol (9:1) as mobile phase. After completion, the reaction mixture was allowed to cool at room temperature. The reaction mixture was quenched in water and neutralized with sodium bicarbonate. The mixture was extracted in ethyl acetate, organic layer washed with brine, dried over sodium sulfate and concentrated completely under reduce pressure at 50° C. The obtained semisolid was purified by preparative HPLC to give 13 mg of N-{3-[(5-fluoro-2-{[4-(2-hydroxyethoxy)phenyl]amino}pyrimidin-4-yl)amino]phenyl}prop-2-enamide.
