Reaction Steps

(1-Pyrimidin-2-yl-cyclopropyl)-carbamic acid tert-butyl ester (1.60 g, 6.80 mmol) was dissolved in CH2Cl2 (10 mL). HCl solution (4M in 1,4-dioxane, 17 mL, 68 mmol) was added via in one portion via syringe and the solution immediately became cloudy. The reaction was allowed to stir for 3 h. Solvents were removed in vacuo yielding a solid mass that was dried under vacuum to give 1.12 g of the title compound as a light yellow solid, m/z 136.32 [M+1]+.
