Conclusions

1. By means of the NMR method it has been shown that tetracycline hydrochloride undergoes rapid epimerization in pyridine solution.

2. The temperature dependence of the constant of the equilibrium TC ⇆ ETC has been studied and the thermodynamic characteristics of this equilibrium have been calculated.

3. The scheme of the transformations of tetracycline hydrochloride leading to the formation of the epimer has been put forward.
