실험 절차

Benzyl 4-[(2-pyrimidinylamino)methyl]-1-piperidinecarboxylate (EXAMPLE 16) was hydrogenated as described in EXAMPLE 30, Step 1. The resulting piperidine was combined with EDC (1.3 equiv.), HOBT (1.0 equiv.), and 4-thiophen-2-yl-butyric acid (1.0 equiv.) in DMF and stirred for 2 h. The resulting reaction solution was partitioned into ethyl acetate and aqueous sodium bicarbonate. The organic layer was separated and washed with pH 4.5 citric acid buffer (10% citric acid and sodium hydroxide), dried (sodium sulfate), and concentrated to yield the desired 1-[4-(pyrimidin-2-ylaminomethyl)-piperidin-1-yl]4-thiophen-2-yl-butan-1-one. M.S. (M+1): 345.25
