Example 1 was repeated except that the 41 grams of triethoxy silane was replaced with 30.6 grams of trimethoxy silane (0.25 mole) and toluene was used as a solvent instead of p-xylene, with other conditions remaining the same. After the completion of the reaction, the reaction mixture was subjected to gas chromatography analysis. It was found that gamma-aminopropyl trimethoxy silane was obtained in a yield of 70% on an allylamine basis, while the yield of beta-amminopropyl trimethoxy silane was 0.9% on an a trimethoxy silane basis.
