Procedure
An ethereal solution of 90 g of chloroacetic acid anhydride is added dropwise to 73.6 g of 5-amino-1,2,3,4-tetrahydronapthalene in 1000 ml of diethyl ether. The temperature should not exceed 30°. The mixture is stirred for a further half hour at room temperature, then cooled to 0° and the precipitated product filtered off. After recrystallisation from ethanol, there is obtained 100 g of 5-chloroacetamino-1,2,3,4-tetrahydronaphthalene having a melting point of 155° - 157° (compound No. 2).
