Reaction Conditions

Reaction Steps

Into a 50 mL round-bottom flask was placed a solution of 1-1,4-dioxaspiro[4.5]decan-8-ylpropan-1-amine hydrochloride (as prepared in Example 104 Step B) (50 mg, 0.21 mmol, 1.00 equiv) in dichloromethane (10 mL) and TEA (42.8 mg, 0.42 mmol, 2.00 equiv). This was followed by the addition of methanesulfonyl chloride (29.1 mg, 0.25 mmol, 1.20 equiv) dropwise with stirring at 0° C. The resulting solution was stirred overnight at room temperature. The reaction was then quenched by the addition of 20 mL of water. The resulting solution was extracted with 2×20 mL of dichloromethane. The organic layers were combined, dried over anhydrous sodium sulfate and concentrated under vacuum to give the title compound as a yellow oil.
