Reaktionsschritte
A solution of 2-methyl-2-nitro-1,3-propanediol and ethylene carbonate is heated overnight. The reaction mixture is diluted with ethyl acetate and the solution is washed with water. The organic phase is dried and concentrated to obtain 5-methyl-5-nitro-1,3-dioxan-2-one. This is dissolved in methanol and hydrogenated under pressure to give the 5amino compound which is acylated with dodecanoyl chloride to give the product.
