Diethyl Ether → 2-[(Cyclopropylmethyl-amino)-methyl]-3,5,7,8-tetrahydro-pyrano[4,3-d]pyrimidin-4-one

tert-butyl cyclopropylmethyl((4-oxo-4,5,7,8-tetrahydro-3H-pyrano[4,3-d]pyrimidin-2-yl)methyl)carbamate (5.639 g, 16.81 mmol) was dissolved in 4 N HCl in dioxane (40 mL) and stirred at room temperature after approximately 5 min a white suspension formed and the reaction was allowed to stir overnight. 100 mL diethyl ether was added and the reaction mixture was filtered, washed with diethyl ether (2×25 mL) and dried in vacuo to yield the title compound as a white solid (4.819 g).
