Reference Example 1 Synthesis of benzyl 4-((2-((tert-butoxycarbonyl)amino)ethyl)(methyl)amino)piperidine-1-carboxylate (0330) (0331) tert-Butyl (2-(methylamino)ethyl)carbamate hydrochloride (0.564 g, 2.68 mmol) and sodium triacetoxyborohydride (0.681 g, 3.22 mmol) were added to a solution of benzyl 4-oxopiperidine-1-carboxylate (0.500 g, 2.14 mmol) in dichloromethane (3.0 mL) at 0 C., and the resulting mixture was stirred at room temperature for 16 hours. The reaction liquid was cooled to 0 C. A saturated aqueous solution of sodium hydrogencarbonate was added to the reaction liquid, and the resulting mixture was extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate and filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, hexane/ethyl acetate) to obtain benzyl 4-((2-((tert-butoxycarbonyl)amino)ethyl)(methyl)amino)piperidine-1-carboxylate (0.590 g, 1.51 mmol, 70%) as a white solid. (0332) 1H-NMR (400 MHz, CDCl3) delta: 1.38-1.46 (11H, m), 1.67-1.76 (2H, m), 2.22 (3H, s), 2.47-2.55 (3H, m), 2.64-2.82 (2H, m), 3.12-3.21 (2H, m), 4.16-4.32 (2H, m), 4.90-5.00 (1H, m), 5.12 (2H, s), 7.30-7.37 (5H, m). (0333) ESI-MS: m/z=392 (M+H)+.
