METHOD FOR OBTAINING MELOXICAM AND POTASSIUM SALT OF HIGH-PURITY MELOXICAM

摘要

The invention relates to a method for obtaining high-purity meloxicam of formula (II). The meloxicam raw product interacts with a solution of potassium hydroxide or potassium carbonate, thus high-purity meloxicam potassium salt monohydrate being produced. After that the said salt is treated with non-organic or organic acid up to obtaining high-purity meloxicam.
