实验步骤: In analogy to the procedure described for the synthesis example 71 (step 1), the title compound (4-chloro-3-cyclopropoxy-phenyl)-[2-(5-trifluoromethyl-pyridin-2-yl)-ethyl]-amine (MS m/e: 357.1 [M+H]+) was prepared from (4-bromo-1-chloro-2-cyclopropoxy-benzene instead of 6-bromo-2,3-dihydro-benzofuran and 2-(5-trifluoromethyl-pyridin-2-yl)-ethylamine instead of 2-(6-trifluoromethyl-pyridin-3-yl)-ethylamine. In analogy to the procedure described for the synthesis example 71 (step 1)

反应条件: temp:150.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 5-bromo-2-chlorophenol (543 mg, 2.62 mmol), bromocyclopropane (836 μl, 10.47 mmol) and caesium carbonate (1.701 g, 5.24 mmol) in N,N-dimethylacetamide (7.5 ml) was stirred for 47 h at 150° C. After 25.25 h further bromocyclopropane (836 μl, 10.47 mmol) was added. The reaction mixture was poured onto ice-water (40 ml) and set to pH=2 with aqueous HCl (1 N, 9.5 ml). This mixture was extracted with TBME (twice 50 ml). The organic layers were washed with brine (40 ml), combined and dried over sodium sulfate. Concentration and purification by chromatography (SiO2, heptane:ethyl acetate=100:0 to 67:33) afforded the title compound (570 mg, 87%) as a light yellow oil. MS m/e: 248.0 [M+H]+ The reaction mixture was poured onto ice-water (40 ml) This mixture was extracted with TBME (twice 50 ml) The organic layers were washed with brine (40 ml) dried over sodium sulfate Concentration and purification by chromatography (SiO2, heptane:ethyl acetate=100:0 to 67:33)
