Participants

Reaction Steps

A mixture of (7RS,8aSR)-7-hydroxymethyl-7-methyl-1,2,3,4,6,7,8,8a-octahydro-pyrrolo[1,2-a]pyrazine (1.08 g, 6.35 mmol), 0.925 g (6.98 mmol) of 2-chloro-5-fluoropyrimidine (Dunaiskis, A.; et al. Org. Prep. Proc. Int., 1995, 27, 600-602), and 1.48 g (13.96 mmol) of sodium carbonate and 65 mL of water was heated at 90° C. for 72 h. the solution was cooled and extracted with chloroform (3×). The combined organic layers were dried (magnesium sulfate), filtered and evaporated. Purification by flash silica gel chromatography eluting with chloroform:methanol (95:5) gave 0.80 g (47%) of the title compound. 13C NMR (CDCl3): a 25.5, 39.5, 41.7, 43.3, 48.7, 51.2, 62.3, 63.8, 71.0, 144.9, 145.2, 149.8, 153.1, 158.9. m/z (MH+) 267.
