Participants

Reaction Steps

A solution of 59 g (0.28 mol of 2-tert.-butyl-2-(tetrahydro-2H-pyran-2-yloxy-methyl)-oxirane in 100 ml of acetonitrile is added dropwise to a mixture of 119 g 1.75 mol of imidazole, 1 g 9 mols) of potassium tert.-butylate and 500 ml of acetonitrile under a nitrogen atmosphere, the reaction mixture being boiled under reflux. When the addition has ended, the mixture is boiled under reflux for a further 10 hours, the solvent is then stripped off under reduced pressure and the residue which remains is taken up in ethyl acetate. The organic phase is washed with water, dried over sodium sulphate and concentrated under reduced pressure. The product thus obtained is purified chromatographically over silica gel with chloroform as the mobile phase. 56.3 g (72% of theory) of 2-tert.-butyl-3-(imidazol-1-yl)-1-(tetrahydro-2H-pyran-2-yloxy)-propan-2-ol are obtained in this manner in the form of a solid substance of melting point 107° C.
