Reaction Conditions:

with Sulfated tungstate at 70; for 0.333333 h;Green chemistry;

Steps:

General procedure for epoxide opening reaction

General procedure: Sulfated tungstate (10 wt%) was added to a solution of cyclohexene oxide (1 g, 10.18 mmol) and aniline (0.95 g, 10.18 mmol) in solvent-free condition and the mixture was stirred at room temperature. The progress of the reaction was monitored by TLC. After the completion of the reaction, the reaction mixture was diluted with ethyl acetate (15 ml) and filtered to recover the catalyst. Organic layer washed with water (10 ml), dried over Na2SO4 and concentrated under reduced pressure to give the crude product which was purified by chromatography on silica gel (60-120) with hexane-ethyl acetate (8:2) as eluent to get pure 2-(phenylamino) cyclohexanol as a white solid.
