Procedure

A reactor connected with a fractionating column and a condenser was charged with 100 g (0.52 mol) of the obtained methyl(N-dimethoxymethylsilylmethyl)carbamate and 13 mg (0.002 mmol) of dibutyltin dilaurate, and the pressure in the system was reduced to 45 mmHg. The mixture was heated to 170° C. While the degradation reaction product methanol was separated and collected, (isocyanatomethyl)dimethoxymethylsilane (OCN—CH2—SiCH3(OCH3)2) was synthesized over 5 hours. The resultant was purified by distillation under reduced pressure to obtain (isocyanatomethyl)dimethoxymethylsilane (yield: 50 g).
