Reaktionsschritte

A mixture of N-(3-{1-[(3S)-3-amino-3-phenylpropyl]-4-piperidinyl}phenyl)-2-methylpropanamide (11.0 mg, 0.0280 mmol) and (4-fluorophenyl)acetyl chloride (7.20 mg, 0.0420 mmol) in THF (5 mL) was stirred at room temperature for 4 h. The solvent was removed under reduced pressure and the residue was purified by preparative TLC using Hexane:EtOAc (2:1) to give the desired product (13 mg, 90% yield). 1H NMR (400 MHz, CDCl3) δ 7.89 (d, 1H, J=8.4 Hz), 7.59 (s, 1H), 7.31–6.93 (m, 13H), 5.13 (q, 1H, J=6.0 Hz), 3.56 (s, 2H), 3.07 (d, 1H, J=11.7 Hz), 2.91 (d, 1H, J=11.0 Hz), 2.62–2.42 (m, 2H), 2.40–2.30 (m, 1H), 2.12–1.54 (m, 9H), 1.24 (d, 6H, J=6.7 Hz); ESMS m/e: 515.3 (M+H)+.
