Abstract
The present invention relates to a complex of agomelatine and to preparation thereof. The hydrogen halide complex of agomelatine obtained through the present method is more soluble, more stable, and of higher purity than agomelatine itself, making it more suitable to be used in pharmaceutical preparation. Using this method, product of high purity can be obtained through a simple process, without having to incur further complicated steps.
