Reaction Steps
A reaction similar to Production example 2-1 using t-Butyl 4-aminopiperidin-1-ylcarboxylate (328 mg, 1.64 mmol), phenyl chloroformate (0.226 ml, 1.80 mmol) and pyridine (0.146 ml, 1.80 mmol); and the obtained crystals were suspended in hexane:ethyl acetate=4:1, filtered off, and the filtrate was purified by silica gel column chromatography (Fuji Silysia BW-300, hexane:ethyl acetate=4:1 to 1:1). The purified crystals were then suspended in hexane:ethyl acetate=4:1 and filtered off. The title compound (215 mg, 0.617 mmol, 40.9%) was obtained as colorless crystals, together with the previously obtained crystals.
