Procedure

[1-(5-Bromo-pyrimidin-2-yl)-cyclopropyl]-carbamic acid tert-butyl ester (1.18 g, 3.76 mmol) was dissolved in CH2Cl2 (5 mL) at room temperature. 4M HCl in dioxane (9.4 mL, 37.6 mmol) was added. After 2 h, the solvents were removed by a stream of N2 to give the title compound as a solid, m/z=216.3. The crude material was used without purification in subsequent steps.
