Triethylsilane → 2-Fluoro-6-(oxiran-2-ylmethoxy)phenol

Participants

Reaction Steps

To a mixture of 2-{[2-(benzyloxy)-3-fluorophenoxy]methyl}oxirane (8 g, 29.2 mmol), ethanol (65 ml) and Pd/C (0.5 g) under N2, triethylsilane (9.3 ml, 58.2 mmol) was added dropwise. The solution was stirred for 16 h at room temperature and filtered through Celite. The solvent was evaporated, Na2CO3 (10%) was added and the solution was extracted with EtOAc. The combined organic phases were dried (Na2SO4) and evaporated to dryness. Flash column chromatography (isooctane/EtOAc) yielded the title compound (3.5 g). MS m/z (rel. intensity, 70 eV) 184 (M+, bp), 153 (44), 139 (31), 128 (99), 57 (23).
