Vorschrift

Compound 3 (R1 =R2 =H) was prepared by a procedure similar to that described in Example 1 by reacting N-methyl-1-phenyl-2-(1H-1,2,4-triazol-1-yl)ethanimine N-oxide (1, R1 =H) with allyl phenyl ether (2, R2 =H). The resulting cis- and trans-diastereomeric mixture of the title compound was flash-chromatographed on neutral silica gel using chloroform-methanol (99:1 by volume) as eluent. Isomer A has a melting point 68°-75° C. (ethyl acetate-hexane, 1:1 by volume).
