Reaction Steps

Into a 50 mL round-bottom flask was placed a solution of 1-(1-1,4-dioxaspiro[4.5]decan-8-ylpropyl)-3-methylurea (as prepared in the previous step, 48 mg, 0.19 mmol, 1.00 equiv) in CH3CN (2 mL), hydrogen chloride (aq, 2M) (2 mL). The resulting solution was stirred for 2 h at room temperature. The pH value of the solution was adjusted to 8 with potassium carbonate (1 mol/L). The resulting solution was extracted with 3×10 mL of dichloromethane. The organic layers were combined, dried over anhydrous sodium sulfate and concentrated under vacuum. The title compound was obtained as a yellow solid.
