It is described epothilone analog of the formula (II) for parenteral administration. The process of preparation thereof comprises the following steps providing that they are carried with protection from light: (a) dissolving of the epothilone analog in a mixture of at least 50 % by volume tertiary-butanol in water preparing a solution； (b) the resulting solutions is primarily dried at temperature from - 10øC to - 40 øC under the conditions of high vacuum during 24 to 96 hours producing lyophilized product； and (c) secondary drying of the resulting lyophilized product is performed at temperature 10 to 30 øC under the conditions of high vacuum during 24 to 96 hours. Pharmaceutical preparation containing the epothilone analog and method of production of the preparation are also described.It is described epothilone analog of the formula (II) for parenteral administration.
