実験手順

A mixture of 2-chloro-5-trifluoromethylpyridine (362 mg, 1.99 mmol) and [1,4]-diazepane (1000 mg, 9.98 mmol) in DMF (6.0 mL) is stirred for 2 hours at room temperature followed by evaporation of the solvent DMF under vacuo. The residue is distributed between ethyl acetate (30 mL) and water (40 mL). The aqueous phase is extracted once with ethyl acetate (20 m) and the combined organic phases are dried with Na2SO4. Evaporation gives an oily residue (crude 1-(5-trifluoromethyl-pyridin-2-yl)-[1,4]-diazepane) which is used directly for reductive amination in the last step.
