Reaction Steps

To a solution of ethyl 4-aminobenzoate (20.00 g, 0.120 mol) and cyclohexanone (17.80 g, 0.180 mol) in tetrahydrofuran (100 ml) and acetic acid (10 ml) was added sodium triacetoxyborohydride (38.50 g, 0.180 mol) at room temperature, and the mixture was stirred for 2 hr. Water was added to the reaction mixture and the mixture was extracted with toluene. The organic layer was successively washed with water, saturated aqueous sodium hydrogen carbonate and saturated brine and dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure, and hexane was added to the obtained residue. The precipitated solid was collected by filtration and washed with hexane. The obtained solid was dried in vacuo to give ethyl 4-cyclohexylaminobenzoate (25.20 g, yield 84%).
