4-(6-Hydroxy-2-morpholin-4-ylpyrimidin-4-yl)-piperidine-1-carboxylic acid tert-butyl ester (0.19 g, 0.52 mmol) was added to 2 N hydrogen chloride in diethyl ether and stirred for 18 hours at room temperature. The resultant product was isolated by filtration and washed with ether to provide 2-morpholin-4-yl-6-piperidin-4-yl-pyrimidin-4-01, hydrochloride salt (0.16 g, 91% yield) as a white solid. 1H NMR (300 MHz, CD3OD/TMS): δ=6.17 (s, 1H), 3.90-3.78 (m, 8H), 3.60-3.50 (m, 2H), 3.26-3.1 (m, 3H), 2.32-2.20 (m, 2H), 2.00-1.80 (m, 2H). 13C NMR (75 MHz, CD3OD/TMS): δ=171.60, 164.86, 155.10, 97.63, 66.93, 45.13, 46.92, 44.81, 38.29, 28.41.
