実験手順
To a solution of (R)-tert-butyl 3-((S)-1-(6-chloro-3′-methylbiphenyl-2-yl)-1-hydroxy-4-(methoxycarbonylamino)butyl)piperidine-1-carboxylate (600 mg, 1.13 mg) in CH3CN (18 mL) was added 2N aq HCl (15 mL) and the reaction mixture was vigorously stirred overnight at rt. The solvents were removed in vacuo to give methyl (4S)-4-(6-chloro-3′-methylbiphenyl-2-yl)-4-hydroxy-4-(piperidin-3-yl)butylcarbamate as its hydrochloride salt (500 mg, 95.8%). 1H NMR (400 MHz, CD3OD): 1.00-1.20 (m, 1H), 1.30-1.80 (m, 8H), 1.80-2.00 (m, 2H), 2.40-2.50 (d, 3H), 2.75-2.90 (t, 1H), 2.90-3.05 (m, 3H), 3.05-3.12 (t, 1H), 3.20-3.30 (m, 1H), 3.30-3.40 (m, 1H), 3.60-3.70 (d, 4H), 6.90-6.98 (d, 1H), 7.00-7.12 (m, 1H), 7.25-7.50 (m, 4H), 7.75-7.85 (d, 1H); MS (E/Z): 431 (M+H+)
