Reference of 104618-32-8, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 104618-32-8 as follows.
Example 11 3-Amino-6-(N-methylsulphonamidomethyl)-1,2,3,4-tetrahydrocarbazole oxalate Reaction of 4-phthalimidocyclohexanone (0.42 g) with 4-(N-methylsulphonamidomethyl) phenyl hydrazine hydrochloride (0.44 g), and subsequent deprotection by the method described in example 3, gave the title compound free base. This was treated with oxalic acid to give the oxalate salt (0.15 g), mp 218-222 C. dec.
