Reaction Steps

To a solution of 2-(3-chloro-4-fluoro-phenylamino)-N-(5-hydroxy-2-methyl-phenyl)-acetamide (0.400 g) and 4-methyl-1-piperazinepropanol (0.270 g) in tetrahydrofuran (20 ml) under a nitrogen atmosphere was added tributylphosphine (0.64 ml) and 1,1′-(azodicarbonyl)dipiperidine (0.656 g) and the mixture stirred at ambient temperature for 20 hours. The reaction mixture was poured into diethylether and filtered through Celite. After concentration, the residue was purified by NPHPLC (eluting with 75% ethanol in dichloromethane) to afford the title compound (0.334 g).
