Lithium hydroxide, monohydrate → (R)-1-[5-(3-chloro-phenyl)-isoxazol-3-yl]-ethanol

Participants

Reaction Steps

The title compound of Example 16.1 (56 g, 211 mmol) and lithium hydroxide monohydrate (10.6 g, 253 mmol) were mixed with THF/Water (7/5, 1.2 L) and stirred at RT over night. Reducing the volume of the mixture in vacuo to about half, followed by dilution with brine, extraction with ether and then drying over MgSO4 and in vacuo concentration gave crude product. The crude product was purified by flash column chromatography on silica using heptane/EtOAc (7:3) to give the title compound (40 g, 85%).
