PROCEDURE

实验过程

To a stirred solution of L-lysine dihydrochloride (1 mmol) in a mixture of THF and 1M K2CO3 (3 mL/3 mL) was added 4-methylbenzenesulfonyl chloride (381 mg, 2.00 mmol). The reaction mixture was stirred for 2 h and then quenched with 1N HCl and extracted twice with EtOAc. The combined organic extracts were dried over MgSO4 and concentrated. The crude was purified by flash chromatography using hexane/EtOAc/AcOH (30:69.4/0.6) to give 75% of the desired product.
