A mixture of cis-2-aminocyclohexanol hydrochloride (4.88 g; 32 mmol) (William S. Johnson and Elliot N. Schubert, J.A.C.S., Vol. 72, pp. 2187-2190 (1950), triphenylmethylchloride (10.7 g; 38.4 mmol) and triethylamine (16 ml; 115 mmol) in 250 ml methylene chloride are refluxed for 3 hrs. then stirred at room temperature overnight. The mixture is poured into H2O and extracted with CH2Cl2 (200 ml), dried (Na2SO4) concentrated in vacuo and flash chromatographed using 9:1 7:1; hexane:EtOAc to obtain cis-2-triphenylmethylaminocyclohexanol which is used directly in the next step.
