実験手順

Methoxylamine hydrochloride (0.88 g, 10.6 mmol) was added to a solution of Example 17A (1.55 g, 9.6 mmol) in pyridine (20 mL) and the mixture stirred overnight at ambient temperature. The mixture was concentrated under reduced pressure and ethyl acetate (200 mL) was added. The organic layer was washed twice with water (200 mL) and brine, dried over sodium sulfate, filtered, and concentrate under reduced pressure. The residue was chromatographed on silica gel eluting with 0-20% ethyl acetate in hexane to afford the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 2.76 (t, J=6.61 Hz, 2H), 2.83 (s, 3H), 3.11 (t, J=6.61 Hz, 2H), 3.87 (s, 3H), 6.69 (t, J=7.46 Hz, 1H), 6.75 (d, J=8.48 Hz, 1H), 7.22 (td, J=7.80, 1.70 Hz, 1H), 7.73 (dd, J=7.80, 1.70 Hz, 1H). MS (DCI) m/z 191.07 (M+H)1.
