Participants

Reaction Steps

(4,4-Difluoro-azepan-1-yl)-(5-phenyl-thiophen-3-yl)-methanone (0.104 g, 0.33 mmol) and N-chlorosuccinimide (0.445 g, 0.33 mmol) in acetic acid (2 mL) were heated by microwave irradiation to 140° C. for 4 minutes. The mixture was diluted with acetonitrile and water and purified by HPLC, eluting with 10%-98% acetonitrile in water (0.1% formic acid). The fractions containing the desired product were evaporated to give the title compound as a gum (0.03 g). LCMS m/z 356.13 [M+H]+ R.T.=12.26 min (Analytical Method 2).
