실험 절차
A mixture of 1-(4-(3-carbomethoxyprop-2-eneoxy) phenyl) propan-2-one (2.27 g) and 2-hydroxy-2-(4-chlorophenyl) ethanamine (1.57 g) in benzene (100 ml) was boiled under reflux with azeotropic removal of water using a Dean and Stark trap. The solution was evaporated, the residue dissolved in methanol (50 ml), cooled in ice and sodium borohydride added. The solution was stirred for 1 hour at 0° C., the methanol evaporated, and the residue partitioned between water and ethyl acetate. The ethyl acetate layer was dried (MgSO4) and evaporated to give a cream solid (3.1 g) which was crystallised from ethyl acetate m.p. 120°-122°. as a 0:100 mixture of diastereoisomers. Recrystallisation of the mother liquors from hexane gave a 70:30 mixture of diastereoisomers, m.p. 55°-65°.
