Reaction Steps

[1-(5-Bromo-pyrimidin-2-yl)-cyclopropyl]-carbamic acid tert-butyl ester (1.18 g, 3.76 mmol) is dissolved in CH2Cl2 (5 mL) at room temperature. A 4M solution of HCl in dioxane (9.4 mL, 38 mmol) is added. After 2 hours, solvents are removed by a stream of N2 to afford crude title compound as a solid, which is used without purification (ES+ m/z 216.3).
