Komponenten

Versuchsvorschrift

To a solution of 3-(2-methoxyethoxy-methoxy)-benzaldehyde (2.10 g, 10 mmol, example 8a) in THF (60 mL) is added methylamine (20 mL, 2M in THF) followed by palladium on carbon (210 mg, 10% Pd). The resulting mixture is stirred for 24 h under an atmosphere of hydrogen gas, then purged with nitrogen, filtered through celite and the filtrate concentrated. The residue is purified by flash chromatography (silica, 10% methanol in dichloromethane) to give the title compound as an oil.
