Reaction Steps

A mixture of 2.52 g (14.8 mmol) of (7R,9aS)-7-hydroxymethyl-2,3,4,6,7,8,9,9a-octahydro-1H-pyrido[1,2-a]pyrazine (Preparation 1), 1.70 g (14.8 mmol) of 2-chloropyrimidine and 6.91 g (65.2 mmol) of sodium carbonate in 150 mL of water was heated at 90° C. for 16 h.; then cooled and extracted with chloroform (3×). The organic layer was dried (magnesium sulfate), filtered and evaporated to give 3.25 g (89%) of the title compound which was used without purification in subsequent reactions.
