Acetic Acid → HCID 15887793, compound

Participants

Reaction Steps

To a solution of Example 9 (0.2 g, 0.49 mmol) in 20 mL of MeOH was added activated MnO2 (0.59 g, 14 equiv.), sodium cyanide (0.05 g, 2 equiv.) and acetic acid (0.05 g, 1.7 equiv.). The resulting mixture was stirred for 5 hours. Tlc monitoring showed a new compound (SiO2,DCM:MeOH (95:5), Rf=0.82). The mixture was filtered through a short column of celite using 150 mL of a mixture of MeOH:EtOAc:CHCl3 (1:25:25). After evaporation in vacuo the residue was purified via flash chromatography on a 2×20 cm2 column using DCM as eluting solvent. Evaporation and recrystallization from EtOH gave the title compound (0.15 g, 70%) as yellow crystals.
