Related Products of 98-61-3, These common heterocyclic compound, 98-61-3, name is 4-Iodobenzenesulfonyl chloride, its 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 solution of (2-methylpropyl)amine (121 mg,1.65mmol) and triethylamine (0.35ml, 2.47mmol) in DCM (10ml) was treated with 4-iodobenzenesulfonyl chloride (500mg,1.65mmol) by dropwise addition over 10 minutes with stirring under argon.The reaction mixture was stirred at room temperature for 16 hr. Then the reaction mixture was washed with water (10ml), separated the organic layer, dried with sodium sulphate.Solvent was removed by rotary evaporation to give the title compound as a white solid (517mg, 92%).LC/Mass Spec (ES): Found 340 (ES+), retention time 3.14mins. C10H14INO2S requires339. 1H-NMR (400MHz, CDCI3): 0.88 (6H, m), 1.72 (1 H, m), 2.78 (2H, m), 4.41 (1 H, m)7.56 (2H, m), 7.88 (2H, m).
The synthetic route of 98-61-3 has been constantly updated, and we look forward to future research findings.
