Reaction Steps

To a solution of (2-morpholin-4-yl-ethoxy)-carbamic acid tert-butyl ester (118 mg, 0.48 mmol) in MeOH (1 mL) is added 4 M dioxane solution of HCl (2.4 mL, 9.60 mmol) at room temperature. The resulting solution is stirred for 16 hours at room temperature. After addition of additional HCl (2.4 mL) followed by stirring for 4 hours, the reaction mixture is concentrated in vacuo to give yellow solids (82 mg, 78%).
