Versuchsvorschrift
Dess-Martin periodinane (2.89 g, 6.82 mmol) and H2O (0.123 ml, 6.82 mmol) are added to DCM (20 ml) and left to stir for 10 minutes. This mixture is treated with 1-(2-methoxy-4-methyl-phenyl)-propan-1-ol (step 1) (1.17 g, 6.49 mmol) in DCM (15 ml) and stirred for 1 hour. The reaction mixture is diluted with DCM and washed with Na2S2O3, NaHCO3, water, brine, dried (MgSO4) and concentrated under vacuum to yield the title product as a clear oil; 1H NMR (400 MHz, CDCl3) δ 7.64 (d, 1H), 6.82 (d, 1H), 6.77 (s, 1H), 3.90 (s, 3H), 3.00 (q, 2H), 2.39 (s, 3H), 1.17 (t, 3H).
