摘要

The present invention relates to a method for producing a gamma-form crystal of silodosin. The method for producing a gamma-form crystal of silodosin according to the present invention has advantages of being safe due to non-use of toluene, which is harmful to the human body; being suitable for mass production and environmentally friendly since the amount of alcohol used in production is relatively small; and being capable of producing a product with uniform quality and a homogeneous crystal.
