Abstract: A process for the preparation of 2-fluoroadenine with a purity of at least 98% (HPLC Area) is presented. Such very high purity degree of at least 98% (HPLC Area) is obtained directly on the crude product after reacting 2,6-diaminopurine in an amount of anhydrous fluorinating agent; heating the resulting reaction mixture; quenching the heated reaction mixture; separating the solid obtained thereby; and washing and separating the solid, without recrystallization and/or any further purification steps.

Abstract: New imidazole derivatives of the formula ##STR1## in which Ar denotes phenyl, biphenylyl, naphthyl or thienyl, each of which is optionally substituted by halogen, lower alkyl or lower alkoxy, R.sub.1 denotes hydrogen or lower alkyl, Alk denotes straight-chain or branched alkylene having 1 to 10 carbon atoms, Y denotes oxygen, sulfur, sulfinyl or sulfonyl, n denotes one of the numbers 0, 1 or 2, Z denotes sulfur or sulfinyl, m denotes the number 0 or 1, m being the number 0 when Y denotes sulfur, sulfinyl or sulfonyl, and m being the number 1 when Y denotes oxygen, and R.sub.2 denotes cyclohexyl, phenyl or naphthyl, each of which is optionally substituted by hydroxyl, halogen, trifluoromethyl, lower alkyl or lower alkoxy, or denotes biphenylyl or pyridyl, and processes for their preparation. The imidazole derivatives have excellent antimycotic properties for use in human and veterinary medicine.
