Reaction Steps

To a solution of azepan-1-yl-[5-(1,2,3,6-tetrahydro-pyridin-4-yl)-thiophen-3-yl]-methanone (0.023 g, 0.08 mmol) in DCM (1 mL) was added triethylamine (0.27 mmol) and acetyl chloride (0.11 mmol). The reaction mixture was stirred for 1 hour, and then the solvent evaporated. The product was purified by HPLC, eluting with 10%-98% acetonitrile in water (0.1% formic acid). The fractions containing the desired product were concentrated under vacuum to give the title compound as a colourless oil (0.009 g). LCMS m/z 333.11 [M+H]+ RT=8.18 min (Analytical Method 2).
