实验步骤: Prepared in a similar manner to example 4 using benzo[1,3]dioxole-5-carboxylic acid and 2-(4-ethyl-phenyl)-ethylamine. MS (M+H, 298.2).

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

实验步骤: Benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (0.650 g, 1.47 mmol) was added to a solution of 2-(4-ethyl-phenyl)-ethylamine (0.235 mL, 1.47 mmol), 4-(2-fluoro-benzyl)-piperidine-1,4-dicarboxylic acid mono-tert-butyl ester (0.330 g, 0.978 mmol) and triethylamine (0.409 mL, 2.93 mmol) in tetrahydrofuran (5 mL). After 1 hour the mixture was diluted with ethyl ether (20 mL) and washed with saturated aqueous sodium bicarbonate (20 mL) followed by water (2×10 mL). The organic layer was collected, concentrated under reduced pressure and crude product purified by column chromatography to give 0.301 g (65%) of 4-[2-(4-ethyl-phenyl)-ethylcarbamoyl]-4-(2-fluoro-benzyl)-piperidine-1-carboxylic acid tert-butyl ester. LRMS m/z 469.1 (M+H)+. washed with saturated aqueous sodium bicarbonate (20 mL) The organic layer was collected concentrated under reduced pressure and crude product purified by column chromatography
