福莫特罗杂质55

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A sample of 3.02 g (11.8 mmol) of 1-(4′-methoxyphenyl)-2-benzylaminopropane (42) was reacted with 1.8 g (11.8 mmol) (S)-(+)-mandelic acid to give 530 mg (35% based on enantiomeric abundance) of the free amine after workup. 1H NMR (CDCl3) δ□ 1.10 (d, 3H, J=6.3 Hz), 2.57-2.76 (m, 2H), 2.88-2.94 (m, 1H), 3.79 (s, 3H), 3.72-3.88 (m, 2H), 6.82 (d, 2H, J=8.7 Hz), 7.07 (d, 2H, J=8.4 Hz), 7.15-7.31 (m, 5H); MS (APCI+) m/z (rel): 256 (100); [α]D=−30.4° (c=1.25 MeOH).
