Reaction Steps

To a solution of 4,4-bis(hydroxymethyl)-3,4-dihydro-2H-benzo[b]oxepin-5-one (500 mg, 2.25 mmol) in 28 ml of tetrahydrofuran were added, at room temperature, triethylamine (0.34 ml, 2.48 mmol) and 2,4-difluorophenyl isothiocyanate (734 μl, 5.63 mmol). The mixture was heated to reflux for 72 hours, concentrated and purified by column chromatography on silica gel (eluent: 1:2 tert-butyl methyl ether/cyclohexane). The product was obtained in a yield of 376 mg (43%).
