7.27 g (0.038) of N-benzyl-3-oxobutyramide were dissolved in a solution of 5.32 g (0.133 mol) of NaOH in 58 ml of water. To the ice-cooled stirred solution, 0.040 mol of phenyldiazonium chloride were added dropwise at such a rate as to keep the temperature at 0° C. The precipitated solid was filtered and recrystallised from MeOH yielding 9 g of the title compound. M.p.=101°-103° C.
