636-76-0,Some common heterocyclic compound, 636-76-0, name is 3-Sulfamoylbenzoic acid, molecular formula is C7H7NO4S, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
a. 3-Sulfamoylbenzoyl chloride 10 g of ground 3-sulfamoylbenzoic acid were reacted as prescribed in Example 70b), the thionyl chloride was distilled off and the residue was crystallized under a mixture of petroleum ether and diethyl ether (1:1). Melting point: 123 C.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-Sulfamoylbenzoic acid, its application will become more common.
