実験手順

In a 100 mL, 2-necked round bottom flask, to a mixture of 1-[(4-{[(tert-butoxycarbonyl) amino]methyl}piperidin-1-yl)methyl]cyclopentanecarboxylic acid (5 g, 14.7 mmol, Step 7) in THF (25 mL), a solution of p-TsOH H2O (8.4 g, 44 mmol) in THF (25 mL) was added at room temperature. The resulting mixture was stirred at 70° C. for 3 h under N2 and it was cooled down to room temperature. To this solution, Et3N (6 mL, 44 mmol) was added dropwise slowly. The white precipitate was formed during the addition of Et3N and the resulting mixture was stirred at room temperature for 14 h. The suspension was filtered and the obtained solid was washed with THF (10 mL), dried at 50° C. for 5 h to give 5.9 g (97%) of the titled compound as a white solid.
