실험 절차

Aqueous sodium hydroxide (2N, 2 mL, 4 mmol) was added to a stirred solution of tert-Butoxy-(2-methyl-4-p-tolyl-5,8-dihydro-6H-7-oxa-9-thia-1-aza-fluoren-3-yl)-acetic acid ethyl ester (66 mg, 0.15 mmol) in ethanol (2 mL) and tetrahydrofuran (2 mL) and the reaction was stirred for 2 hours at 60° C. The reaction was concentrated in vacuo until only the aqueous remained. The pH was adjusted to 2 by the addition of 2N aqueous HCl. The resulting solid was collected by filtration and purified by preparative HPLC to afford the title compound. LCMS 3.63 min, ES+/AP+ 425.1 (MH+).
