実験手順

In a reaction flask, 100 ml of aqueous ammonia and 100 ml of dioxane were added, and a solution of 17.9 g 2-benzyloxyformamidoethylsulfonyl chloride in acetonitrile (30 ml) was added dropwise under ice-bath condition. The mixture was stirred for 2 h at room temperature. Upon the end of the dropping, the mixture was concentrated under a reduced pressure, and was then filtered, the filter cake was washed with water, and dried to obtain 12.3 g of white solid, yield 74%.
