Reaction Conditions:

with sulfuric acid for 8 h;Reflux;

Steps:

2 4.3.1 Synthetic procedure of methyl 4-sulfamoylbenzoate (6)

Commercially available, 73 4-sulfamoylbenzoic acid 5 (10mmol) was refluxed in dried 74 methanol with a catalytic amount of 75 conc. H2SO4 acid for 8h. After completion of the reaction, the mixture was poured into ice cold water and obtained precipitate was filtered and dried to give 11 methyl 4-sulfamoylbenzoate 6. 4.3.2 11 Methyl 4-sulfamoylbenzoate (6) (0035) White crystalline solid; yield 95%; mp: 148-150°C; 1H NMR (DMSO-d6,400MHz):δ 3.87 (s, 3H, OCH3), 7.55 (s, 2H, NH2), 7.94 (d, 2H, Ar, J=8.4Hz), 8.12 (d, 2H, Ar, J=8.4Hz); LC-MS: m/z; 216 (M+1).
