Versuchsvorschrift

To a slurry of intermediate 13 (0.45 g, 1.3 mmol), 3-azetidinol hydrochloride (0.3 g, 2.7 mmol) and triethylamine (0.76 mL) in 50 mL of dichloromethane, was added NaBH(OAc)3 (0.86 g, 4.5 mmol) at room temperature. The reaction was stirred for 12 hour at room temperature and then quenched with 1N—NaOH. It was extracted with dichloromethane (×2) and washed with brine. The collected organic layers were dried over anhydrous sodium sulfate and then concentrated in vacuo. The resulting residue was purified by column chromatography to afford desired Compound No. 143 as a pale yellow solid (0.27 g, 51%); MS (ESI) m/z 391 [M+H]+.]+; 1H NMR (300 MHz, DMSO-d6) δ 9.75 (s, 1H), 8.48 (d, 1H, J=5.4 Hz), 8.30 (s, 1H), 8.21 (s, 1H), 7.99 (s, 1H), 7.62 (m, 2H), 7.12 (d, 1H, J=5.4 Hz), 5.34 (m, 1H), 4.19 (m, 1H), 4.04 (s, 3H), 3.49 (m, 2H), 3044 (s, 2H), 2.77 (m, 2H), 2.29 (m, 3H).
