Reaction Steps

Into a 10-mL sealed tube, was placed 5-(4-ethylphenyl)-2H-1,3,4-oxathiazol-2-one (155 mg, 0.75 mmol, 1.00 equiv), ethyl 4,4,5,5,5-pentafluoropent-2-ynoate (250 mg, 1.16 mmol, 1.55 equiv), 1,3-dichlorobenzene (3 mL). The resulting solution was stirred for 16 h at 150° C. in an oil bath. The reaction progress was monitored by LCMS. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:19). The resulted in a mixture of the product 0.192 g as the yellow oil. Mass spectrum (ESI, m/z): Calcd. for C16H14F5NO2S, 380.3 (M+H). found 380.3.
