[5-amino-4-fluoro-2-(1-methylcyclohexyl)phenyl] methyl carbonate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 4-fluoro-2-(1-methylcyclohexyl)-5-nitrophenyl methyl carbonate 24.1 g, 77.5 mmol) in 220 mL of CH3OH was added Pd/C 10%, 9.6 g, then ammonium formate (26.7 g, 445 mmol) was portion-wise added to the above reaction mixture at room temperature until starting material is consumed. The mixture was filtrated and the filtrate was evaporated under vacuum. The residue was purified by column chromatography on silica gel diluted with hexane:ethyl acetate=50:1 to give 5-amino-4-fluoro-2-(1-methylcyclohexyl)phenyl methyl carbonate as a red brown oil (17.9 g, 82% yield). 1H NMR (400 MHz, CDCl3) δ 6.99 (d, J=13.6 Hz, 1H), 6.51 (d, J=8.4 Hz, 1H), 3.89 (s, 3H), 3.43 (brs, 2H), 1.96-1.91 (m, 2H), 1.58-1.38 (m, 8H), 1.18 (s, 3H): MS m/z: 281.9 [M+H]+ added to the above reaction mixture at room temperature is consumed The mixture was filtrated the filtrate was evaporated under vacuum The residue was purified by column chromatography on silica gel diluted with hexane
