Phenylacetyl isocyanate → HCID 23153375, compound

Participants

Reaction Steps

To a solution of 4-(4-amino-2-fluorophenoxy)-2-{[4-(2-dimethylaminoethyl)piperazin-1-yl]carbonylamino}pyridine (87.4 mg) in tetrahydrofuran (4.5 ml) was added a solution of 2-phenylacetyl isocyanate in hexane (0.25 M, 2.2 ml) at room temperature, followed by stirring overnight. The reaction mixture was partitioned between ethyl acetate and a saturated aqueous solution of sodium hydrogencarbonate. The organic layer was washed with brine and dried over anhydrous sodium sulfate. The solvent was evaporated to give a residue, which was then purified by silica gel column chromatography (Fuji Silysia NH, eluent; ethyl acetate, then ethyl acetate:methanol=95:5) to provide the titled compound (82 mg, 67%) as white powder.
