The mixture was cooled to 0° C. and treated in succession with water (4.4 mL), tetrahydrofuran (200 mL), 15% sodium hydroxide solution (4.4 mL), and water (13.3 mL). The mixture was filtered and the filter cake was rinsed with ethyl acetate. The filtrate was concentrated under reduced pressure to provide the title compound. MS (DCI/NH3) m/z: 203 (M+H)+.
