Reaction Steps

In a 500 ml, three-neck, round-bottom flask equipped with a thermometer, stirrer and a Stark and Dean trap with condenser were placed 119.4 g of methyl stearate, 41 g of 3-amino-2,2-dimethylpropanol and 3 g of potassium tert-butoxide. The mixture was heated to 190° C., and the methanol distilled off. The reaction mixture was dissolved in hot isopropanol and filtered. On cooling, the product crystallized, and after filtration and drying it melted at 44° C. IR showed an ester carbonyl. The pure product was obtained by washing with hot hexane. The pure product melted at 68°-69° C.
