Procedure

Into the same reactor as used in Example 1, 54.7 parts of allylamine, 1.0 part of phenothiazine and 0.0005 part as platinum atom of the same platinum complex as in Example 1 were charged, 100 parts of dimethylethoxysilane were added at 50° C. through the dropping funnel over 20 minutes, and the reaction was completed by elevating the temperature to 125° C. over 4 hours. After cooling, 5.5 parts of ethanol were added, and distillation was carried out to give 87.8 parts of γ-aminopropyldimethylethoxysilane boiling at 75° to 77° C./18 Torr. This corresponded to 55% yield based on the theoretical amount.
