실험 절차
(S)-Piperidine-1,3-dicarboxylic acid 1-tert-butyl ester (20 kg, 87.2 mol) was slurried in acetic acid (189 kg) and cooled to 15° C. An excess of hydrogen chloride gas (9.6 kg) was charged and stirred for ˜4 hours to complete deprotection. The slurry was isolated and filter-cake rinsed with acetic acid (2×31.5 kg). The filter cake was then vacuum dried to obtain product (14.4 kg).
