실험 절차
A solution of 2, 6 difluorobenzamide (1 eq) and Lawesson's reagent (0.5 eq.) in toluene (0.2 M) was heated at 90° C. for 14 hours. Upon cooling the volatiles were removed in vacuo and purified by SiO2 chromatography (25% EtOAc/hexanes) yielding 2,6-difluorobenzothioamide as a light yellow solid (99%). LCMS (m/z): 174.1 (MH+); LC Rt=2.19 min.
