Reaction Steps

As a further illustration, Scheme 28, Example 2 depicts the reaction of the chloro-propyl tetrahydropyrimidine derivative 28.13 with potassium phthalimide 28.16. Equimolar amounts of the reactants are combined in dimethylformamide at ca 80°, in the presence of a catalytic amount of potassium iodide, to afford 2-{3-[3-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-propyl]-2-oxo-tetrahydro-pyrimidin-1-yl}-3-methyl-butyric acid 28.17. The product is then reacted under reductive amination conditions, as described above (Scheme 10) with a dialkyl formylphenyl phosphonate 28.19 (Epsilon) to yield the phosphonate ester product 28.20.
