Reaction equation

[CH2:1]([NH2:4])[CH:2]=[CH2:3].C1C2NC3C(=CC=CC=3)C=2C=CC=1.[CH3:18][SiH:19]([O:22][CH3:23])[O:20][CH3:21]>C(O)C>[NH2:4][CH2:1][CH2:2][CH2:3][Si:19]([CH3:18])([O:22][CH3:23])[O:20][CH3:21]

Conditions

Temperature: 60 °C

Procedure

Into the same reactor as used in Example 1, 17.1 parts of allylamine, 0.3 part of carbazole, 0.00005 part as platinum atom of the same platinum complex as in Example 1 were charged, 31.8 parts of methyldimethoxysilane were added dropwise at 40° C. over 5 minutes, followed further by continuing stirring for 4 hours while maintaining the liquid temperature at 60° C. After cooling, 1.7 parts of ethanol were added and distillation was carried out to give 36.2 parts of γ-aminopropylmethyldimethoxysilane boiling at 105° to 109° C./50 Torr. This corresponded to 74% yield based on the theoretical amount.
