Procedure

The condensation reaction of 11.9 g of 7-cyanoheptanal dimethylacetal and 4.35 g of pentaerythritol was carried out to obtain 13.6 g of 3,9-bis(6-cyanohexyl)-2,4,8,10-tetraoxaspiro[5.5]undecane, which was then subjected to catalytic reduction to form 8.6 g of 3,9-bis(7-aminoheptyl)-2,4,8,10-tetraoxaspiro[5.5]undecane.
