Sodium metaborate → 1-(4-Allyloxyphenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-2-butanol

Participants

Reaction Steps

1 g (0.027 mole) of sodium boranate is added in portions to 7.2 g (0.023 mole) of 1-(4-allyloxyphenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-2-butanone (Example 1) in 80 ml of methanol at 20° C., while stirring. The mixture is subsequently stirred for 1 hour and is then concentrated in vacuo by distilling off the solvent. The residue is partitioned between methylene chloride and water. The organic phase is separated off, dried over sodium sulphate and concentrated in vacuo. 7 g (97.2% of theory) of 1-(4-allyloxyphenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-2-butanol of melting point 85° C. are obtained.
