20 g of dimethoxy-(2-propylpyrimidin-5-yl)-borane (obtained from 2-propylpyrimidin-5-ylmagnesium chloride and trimethoxyborane) and 30 g of 2-hydroxymethylnonan-1-ol are heated at 100° for 12 hours, the methanol formed being removed continuously by distillation. When the reaction is complete, excess nonanol is removed under reduced pressure, and 2-(2-propylpyrimidin-5-yl)-5-heptyl-1,3,2-dioxaborinane is obtained.
