The present invention discloses a method for preparing a high-purity sulfonamide compound and an intermediate of the sulfonamide compound. The method comprises the following steps: a, taking a crude product of a sulfonamide compound (I) as an initial raw material, and enabling the raw material to react with a compound of a formula (II) in presence of alkali and a catalyst so as to synthesize an intermediate of a formula (III); and b, enabling the compound represented by the formula (III) to react with alkali or acid, thereby obtaining the high-purity sulfonamide compound (I).

Provided herein are a biarylsulfonamide, e.g., a compound of Formula (IA), and a pharmaceutical composition thereof. Also provided herein is a method of treating a fibrotic lung disease with a biarylsulfonamide, alone or in combination with an antifibrotic agent. Additionally, provided herein is a method of slowing the rate of decline in pulmonary function in a subject having a fibrotic lung disease with a biarylsulfonamide, alone or in combination with an antifibrotic agent.
