Procedure

To a 500 ml three neck flask fitted with a reflux condenser and dropping funnel is added 55.6 g (0.25 mole)(of N-2-aminoethyl-3-aminopropyltrimethoxysilane. To this is added slowly a mixture of 70% phosphorous acid (0.5 mole), deionized water, and concentrated hydrochloric acid (60 grams). The mixture is heated to gentle reflux and 37% aqueous formaldehyde (0.50 mole) is added dropwise during one hour. The mixture is heated for an additional hour to complete the reaction.
