Versuchsvorschrift

To a solution of 4-(2-pyrrolidin-1-yl-ethoxy)-phenylamine (6.92 g, 33.5 mmol) and 4-(tetrahydro-pyran-2-yloxy)-benzaldehyde (7.25 g, 35.2 mmol) in 110 mL methylene chloride was added magnesium sulfate (14.2 g, 117.3 mmol). The reaction mixture was stirred at room temperature overnight under nitrogen. The reaction was filtered and concentrated to afford 13.3 g of the crude title compound of Step A which was used without further purification. MS 395.2 (M+1)+

Aufarbeitung

  1. filtrationThe reaction was filtered
