Reaction Steps
Following a literature procedure (Zoidis et al., Bioorg. Med. Chem. 2009, 17, 1534-1541), the title compound of Example 18 (0.015 g, 0.034 mmol) was dissolved in anhydrous THF (0.34 mL) and cooled to 0° C. A solution of LAH (0.10 mL, 1.0 M in THF) was added dropwise, and the reaction was stirred for 2 h at 0° C. MeOH was added to quench the remaining LAH and after 45 min, the mixture was partitioned between EtOAc/H2O. The organic layer was separated and the aqueous layer was extracted with EtOAc (3×), and the combined organic layers were washed with satd. aq. NaCl, dried over Na2SO4, filtered, and concentrated. The crude residue was purified by column chromatography (SiO2, 0-20% MeOH/Acetone+1% Et3N), followed by PTLC (10% MeOH/Acetone+1% Et3N) to afford the desired product (0.6 mg, 5%).
