4-Methylbenzylsulfonyl chloride

General procedure: Alkyl halide (or sulfate) (5 mmol) and thiourea (0.381 g, 5 mmol) were heated at reflux in EtOH (5 mL) for 1 h. After removal of the solvent in vacuum and washing with EtGeneral procedure: Step 1. An alkyl halide or mesylate (5 mmol) and thiourea (0.381 g, 5 mmol) wererefluxed in 5 mL of ethanol for 1 h. After removal of the solvent in vacuum thecorresponding S-alkyl isothiourea salt was obtained as white solid or sticky oil.Step 2. A 50 mL three-necked flask equipped with a thermometer and asolid-addition funnel was immersed in an ice-bath. To the flask was sequentiallyadded NaClO2 solid (for isothiouronium chlorides or sulfonate, 1.61 g, 15 mmol; forisothiouronium bromides, 2.14 g, 20 mmol, 85percent purity), MeCN (10 mL), and thenconc. HCl (for isothiouronium chlorides or sulfonate, 3 mL; for isothiouroniumbromides, 4 mL) during 1 min at such a rate that the inner temperature was maintainedless than 10 °C. Then S-alkyl isothiourea salt was slowly added througth the solidaddition-funnel to keep the inner temperature less than 20 °C. After the addtion, theresulting mixture was stirred for another 30 min. Then 25 mL of water was added, and the resultant mixture was evaporated in vacuum at 15 °C to remove acetonitrile. Afteraddition of 100 mL of water, the solid products were obtained by filtration on aBuchner funnel and dried under an infrared lamp, while the liquid products wereobtained by extraction with 15 mL of ethyl acetate, drying with Na2SO4, andconcentration in vacuum.For 1, 4-dibromobutane, the amounts of thiourea, NaClO2 solid, MeCN, and conc.HCl were doubled.General procedure: The appropriate alkyl halide (or mesylate) (5 mmol) and thiourea (0.381 g, 5 mmol) were refluxed in EtOH (5 mL) for 1 h. After removal of the solvent in vacuum and washing with EtGeneral procedure: A two-step one-pot method for preparing an abscisic acid receptor agonist:Add p-methylbenzyl mercaptan to acetonitrileAnd then adding a chlorinating reagent, Point plate monitoring, after the reaction, move into the ice water bath, Add 4 equivalents of an acid binding agent such as pyridine.After the addition, 7-amino-N-propylquinolinone in acetonitrile was slowly added dropwise.The plate is monitored for reaction, after the reaction, pickling, drying, Further, the abscisic acid receptor agonist can be obtained by column chromatography or recrystallization,
