The closest to the described method is the method of producing compounds of formula I, which consists in that the silylated eJ-aminosilane, namely W - (trimethylsilyl) -M- (alkyl) ammonium methyl alkoxydialkylsilane is reacted with carbon dioxide at 20-. 2. The disadvantages of this method include the preliminary silyl protection of carbaminosilane, which is associated with the need to dispose of NH CE and ammonia. The aim of the invention is to simplify the process. This goal is achieved due to the fact that kXi-aminosilane of the general formula 1 n N- ' iH-i -OCH3, / H 5 K is hydrogen, alkyl with Cd-Cd allyl is reacted with diethylcarbamic acid trimethylsilyl ether. A distinctive feature of the proposed method is the reaction (X, α-aminosilane of the general formula.
