(6S)-6-C-(4′-{(2S,3R)-3-[(3S)-3-(4-Fluorophenyl)-3-hydroxypropyl]-4-oxo-1-phenylazetidin-2-yl}-3′-hydroxybiphenyl-3-yl)-D-glucopyranose (7.1 mg, 0.01 mmol) was dissolved in 80:20 acetonitrile-water (1 mL). Sodium borohydride (0.4 mg, 0.01 mmol) was added at room temperature and the reaction was stirred for 30 min monitoring by LCMS. Upon completion, the reaction was diluted with 80:20 acetonitrile:water (3 mL) then filtered through a Whatman 0.45 μM glass microfiber filter and purified by reverse-phase HPLC (Polaris C18-A 10 μ 250×21.2 mm column, 30% to 95% acetonitrile-0.1% trifluoroacetic acid in water) to afford (6S)-6-C-(4′-{(2S,3R)-3-[(3S)-3-(4-fluorophenyl)-3-hydroxypropyl]-4-oxo-1-phenylazetidin-2-yl}-3′-hydroxybiphenyl-3-yl)-D-glucitol (1.4 mg, 22% yield). 1H NMR (300 MHz, CDCl3/CD3OD) δ 7.37-6.89 (m, 16H), 5.08 (d, J=2.4 Hz, 1H), 4.97-4.95 (m, 1H), 4.60 (t, J=6.0 Hz, 1H), 3.92 (m, 1H), 3.76-3.56 (m, 6H), 2.01-1.82 (m, 4H) ppm; MS [M−OH]+ 629.8.
