Versuchsvorschrift

Derivative 3 (R=H, n=5) is prepared by a procedure similar to that described in Example 1 by reacting 1-phenyl-N-methyl-2-(1H-1,2,4-triazol-1-yl)ethanimine N-oxide (1: R=H) with 1-octene (2: n=5). The resulting cis- and trans-diastereomeric mixture of compound 3 (R=H, n=5) is flash-chromatographed on neutral silica gel using as eluent a 98:2 by volume mixture of chloroform-methanol. Isomer A has a melting point of 93°-99° C. (ethyl acetate).
