실험 절차

A solution of 3-acetamido-6-chloro-2-fluorobenzyl methanesulfonate (1.31 g, 3.54 mmol) in DMSO (10 mL) was treated with sodium cyanide (0.868 g, 17.72 mmol), stirred at RT overnight, treated with water and extracted with EtOAc (2×). The combined organics were washed with brine, dried over Na2SO4, concentrated to dryness and purified via silica gel chromatography (EtOAc/Hex) to afford N-(4-chloro-3-(cyanomethyl)-2-fluorophenyl)acetamide (630 mg, 78% yield) as a yellow solid. MS (ESI) m/z: 227.0 [M+H]+.
