Trifluoroacetic acid → HCID 22106272, compound

Participants

Reaction Steps

To a solution of N-[(1-tert-butoxycarbonylmethyl)-4-(3-methoxyphenyl)-1,2-dihydro-2-oxo-1,8-naphthyridin-3-yl]-N'-(2,6-diisopropylphenyl)urea (110 mg, 0.19 mmol) in methylene chloride (20 ml) was added trifluoroacetic acid (1 ml, 13 mmol), and the mixture was stirred at room temperature for 1.5 hour. The mixture was concentrated under reduced pressure, diluted with water, and basified with 4N aqueous NaOH solution, and washed with ethyl acetate. The aqueous layer was acidified with 2N aqueous HCl solution, extracted with ethyl acetate, washed with a saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The residue was concentrated under reduced pressure, and purified by preparative thin layer chromatography to give the title compound (41 mg, 0.77 mmol).
