참여 물질

반응 단계

To the product of Step A (1.5 g, 10.19 mmol) in THF (15 mL) was added 4-methoxyphenylmagnesium bromide (11.21 mL, 11.21 mmol, 1.0 M). The reaction aged at rt for 3.5 h and was concentrated. The residue was dissolved in MeOH (20 mL) and then slowly treated with NaBH4 (0.386 g, 10.19 mmol). The reaction was stirred at rt overnight, concentrated and treated with aq. HCl (15 mL, 30 mmol, 2.0 M). The aqueous portion was extracted with EtOAc (2×) and the combined organic layers were washed with a 1:1 solution of aq. 2.0 M NaOH/brine, dried (MgSO4), filtered and concentrated. The residue was purified by flash chromatography on silica gel gradient eluted with 0-100% EtOAc/hexane to afford the title compound. HPLC/MS: 241.0 (M—NH2)+; Rt=1.91 min.
