In a stirring and distillation apparatus according to Example 1, 202.8 g of N-methylbenzamide (1.5 mole) were dissolved in 1500 g of anhydrous toluene at 65° C., and 321.1 g of sodium methanolate solution (25.25% strength, 1.5 mole) were run in, the process was carried out in accordance with Example 6. Then 259.2 g of methyldiethoxychlorosilane (97% pure 1.49 mole) wer slowly added dropwise, and the bottom temperature was maintained at 70° C., and the mixture was then stirred at this temperature for 3 h.
