Methanaminium, N-((dimethylamino)(3H-1,2,3-triazolo(4,5-b)pyridin-3-yloxy)methylene)-N-methyl-, hexafluorophosphate(1-) (1:1) → (4,4-Difluoro-azepan-1-yl)-(5-phenyl-thiophen-3-yl)-methanone

Participants

Reaction Steps

5-Phenyl-thiophene-3-carboxylic acid (0.20 g, 1.11 mmol) and 4,4-difluoro-azepane hydrochloride (0.19 g, 1.11 mmol) were stirred in acetonitrile (10 mL) with silica-supported diethylamine (1.32 mmol/g, 2.5 g) and HATU (0.40 g, 1.11 mmol) for 18 hours. The reaction mixture was filtered and the solvent was removed by evaporation then the crude material was purified by HPLC, eluting with 10%-98% acetonitrile in water (0.1% formic acid) over 20 minutes. The fractions containing the desired product were evaporated to give the title compound as a gum (0.15 g). LCMS m/z 322.19 [M+H]+ R.T.=11.14 min (Analytical Method 2).
