Procedure
195 ml chloroacetyl chloride in 200 ml 2-methyltetrahydrofuran are added dropwise at 2° C. within one hour to a mixture of 300 ml (methylamino)-acetaldehyde dimethylacetal, 1200 ml 2-methyltetrahydrofuran and 1200 ml saturated potassium carbonate solution. After 40 min 1450 ml of water are added and the phases are separated. The aqueous phase is extracted with 600 ml 2-methyltetrahydrofuran. The combined organic phases are dried on sodium sulphate and evaporated down. 451 g product remain.
