Procedure
In a 250 ml round bottom flask equipped with a reflux condenser and a Dean-Stark trap, 6.91 g of racemic trans-2-aminocyclohexanol (60 mmol) obtained according to (b) were dissolved under argon in 70 ml of diisopropyl ether and 6.1 ml of benzaldehyde (60 mmol) were added to the solution which was refluxed under argon at 110° C. during 50 min until about 1 ml of water separated. The solvent was removed in a rotary evaporator (45° C./250-10 mbar) to obtain 12.11 g of white-beige crystals of racemic trans-2-(benzylidenamino)-cyclohexanol, m.p. 86° C.
