Reaction Steps

To a melt of urea (748 mg, 12.45 mmol) at 150° C. was added ethyl 2-oxo-3-(6-(trifluoromethyl)pyridin-3-yl)cyclopentanecarboxylate (750 mg, 2.49 mmol) dropwise. The reaction was stirred overnight. The reaction mixture was cooled and the resulting solid mass was broken up and suspended in MeOH. The mixture was diluted with a large excess of water and cooled in an ice bath. The suspension was filtered and the residue was washed with water and dried to afford the semi-pure product, 7-(6-(trifluoromethyl)pyridin-3-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine-2,4-diol (334 mg, 1.124 mmol, 45.1% yield). LC-MS (M+H)+=298.0.
