Versuchsvorschrift

A stirred solution of 1-bromo-5-fluoro-4-nitro-2-(trifluoromethyl)benzene (D53) (0.30 g, 1.04 mmole) in dimethylformamide (5 ml) at room temperature under argon was treated with diisopropylethylamine (0.59 ml, 3.3 mmole) and 1-(tetrahydro-2H-pyran-4-yl)-4-piperidinamine dihydrochloride (D40) (0.28 g, 1.1 mmole) and heated at 70° C. for 1 hr. The mixture was concentrated under vacuum and the residue treated with 10% Na2CO3 solution and extracted with ethyl acetate. The extract was dried and concentrated under vacuum to leave an orange solid which was purified by chromatography on silica gel eluting with 0-20% methanol/ethyl acetate to afford the title compound as a bright yellow solid (0.38 g, 81%). MH+=452, 454.
