実験手順

A solution of chloroacetyl chloride (0.1 mole, 11.3 g) in benzene (40 ml) was added over 30 min to a mixture of sarcosinamide hydrochloride (0.1 mole, 12.45 g) and sodium bicarbonate (0.25 mole, 20.0 g) in 40 ml of water. The mixture was vigorously stirred for 3 h at room temperature. The aqueous phase was acidified with 5M hydrochloric acid to pH 5 and extracted with ethyl acetate (3×400 ml). The combined extracts were dried over anhydrous sodium sulphate and evaporated in vacuo. The solid residue obtained was recrystallized from ethanol-ether to give 8.5 g (52%) of the title compound. Mp 85°-86° C.
