実験手順
A mixture of 3 g (14.78 mole) of dibromoformaldoxime and 2.71 g (15.5 mole) of 4-chlorobenzoyl chloride in methylene chloride (40 ml) is treated with dry pyridine (1.26 g, 16 mole) After workup as in Step B of Example 1 there is obtained 4.4 g (80% theory) of 4-chlorobenzoyldibromoformaldoxime, m.p.=93°-97° C.
