Versuchsvorschrift

151 (616 mg) was dissolved in 4 ml of DCM and 4 ml of TFA was added then the reaction mixture was let 1 h at room temperature. The reaction mixture is concentrated and 50 ml of AcOEt are added. The organic phase are washed with saturated NaHCO3 and brine then dried over Na2SO4, filtered and concentrated to afford 152 as an oil (324 mg, 88%). 1H NMR (DMSO): δ 0.99 (t, 3H, J=7.3 Hz), 2.82 (m, 2H), 4.61 (s, 2H), 6.50 (t, 1H, J=5.8 Hz), 7.32 (m, 5H).
