4-hydroxy-N-methoxy-N-methyl-3-(morpholinomethyl)benzamide → 4-Hydroxy-3-morpholin-4-ylmethyl-benzaldehyde

Participants

Reaction Steps

Bis(cyclopentadienyl)zirconium chloride hydride (4.29 g, 16.27 mmol) was added portionwise over 10 min to a solution of 4-hydroxy-N-methoxy-N-methyl-3-(morpholinomethyl)benzamide (3.8 g, 13.56 mmol) in THF (50 mL), under N2 whilst maintaining the temperature below 20° C. Stirred for 2 h, quenched with saturated potassium sodium tartrate, extracted with EtOAc (3×100 mL), washed with more saturated potassium sodium tartrate and brine, dried (Na2SO4), filtered and evaporated in vacuo. Purified by flash chromatography with EtOAc as eluent to give the sub-title compound as a colourless oil. Yield: 2.1 g
