Procedure
Dissolve 1 g. of amino product produced in Example 35 in 20 ml. of dry pyridine. Cool in an ice-bath and stir while slowly adding 300 mg. of ethyl chloroformate. Allow the reaction mixture to stand at room temperature overnight. Pour the reaction mixture into ice-water and collect the crude product by filration. Crystallize the crude product from dimethyl formamide-ether.
