136-90-3, The chemical industry reduces the impact on the environment during synthesis 136-90-3, name is 4-Methoxy-3-methylphenylamine, I believe this compound will play a more active role in future production and life.
Compound 107 3-[[(3S)-tetrahydrofuran-3-yl]sulfamoyl]benzoic acid (270 mg, 1.0 mmol) was dissolved in dichloromethane (5 mL). 3-methyl-4-methoxyaniline (165 mg, 1.2 mmol) and triethylamine (145 mg, 1.4 mmol) were added to the mixture at 20C. The mixture was stirred at 20C for 5 minutes. HATU (456 mg, 1.2 mol) was added and the mixture was further stirred at 20C for 8 hours. The solvent was removed in vacuo and the obtained residue was purified by high performance liquid chromatography (Column: Phenomenex Synergi C18 150*20mm*5um.. A: H2O+0.1%TFA B: MeCN from 30% to 60 % B in A). The product fractions were collected and the organic solvent was evaporated in vacuo. The aqueous layer was neutralized with saturated aqueous NaHCC>3 and extracted with dichloromethane (2 x 10 mL). The combine organic layers was dried over Na2S04 and concentrated in vacuo resulting in compound 107 (135 mg). Method A; Rt: 5.24 min. m/z : 391.3 (M+H)+ Exact mass: 390.1
