Iodoethane → N-(4-(2-ethylbutanoyl)phenyl)acetamide

Participants

Reaction Conditions

Reaction Steps

To a solution of N-(4-butyrylphenyl)acetamide (3 g, 14.6 mmol) in THF (300 mL) was added 2.0 M LDA in THF (18.3 mL) at −78° C. and then the reaction mixture was stirred for 1 h at −78° C. Iodoethane was added and stirred overnight at RT. The reaction mixture was quenched with sat. aq. NH4Cl and then extracted with ethyl acetate. The combined organic layers were dried over MgSO4, filtered and then concentrated. The crude product was purified by preparative TLC using 50% ethyl acetate in hexane as eluent to afford N-(4-(2-ethylbutanoyl)phenyl)acetamide as white solid. MS (ES+): m/z 234.28 (MH+).
