Yield:596-51-0 144 g

Reaction Conditions:

in acetonitrile at -10 - 20; for 12 h;

Steps:

1.4; 1.5

260 g of intermediate III obtained in step 3 was dissolved by heating to 310 g of acetonitrile, cooled down to -10 DEG C, 167 g of methyl bromide was introduced, and the temperature was raised to room temperature for 12 hours.Filtration gave 311 g of crude glycopyrrolate; The crude glycopyrrolate was recrystallized from butanone to obtain 144 g of glycopyrrolate qualified product.The yield of the target product was 42.1% in one step, and the total yield was 36.1%. The purity of the product was >99.0% as determined by HPLC.
