실험 절차

To a stirring solution of N,N-diethyl-4-propylbenzamide (2.0 g, 9.3 mmol) and N,N,N′N′-tetramethylethylenediamine (1085 mg, 9.4 mmol) in dry THF (93 mL) at −78° C. under Ar was added 0.78 M s-butyllithium in hexanes (12 mL). The reaction was stirred for 30 min and then methyl disulfide (1936 mg, 12.1 mmol) was added. The reaction was stirred for 5 min and then quenched with MeOH (1 mL) and brine. The reaction was extracted with EtOAc (3×50 mL). The organic layers were combined, dried over Na2SO4, and conc in vacuo to a yellow oil. The oil was purified by flash chromatography (SiO2, 0-30% EtOAc in hexanes) to yield 2.1 g (86%) of the product as a yellow oil. MS (ESI) 266 (M+H).
