실험 절차

The amide of Example 53 (2.8 g, 0.01 mole) in dimethylformamide (25 ml.) was added to sodium hydride (0.0105 mole) (from 40-50% NaH in oil, 0.74 g) which was stirred in dimethylformamide (25 ml.) and cooled in ice. The mixture was stirred for 0.5 hr. and treated with a solution of p-chlorobenzyl chloride (3.22 g, 0.02 mole) in DMF (15 ml.) and a trace of NaI. The mixture was stirred, initially at ice-bath temperature and them at room temperature overnight and then refluxed for 3 hours to complete the reaction. The DMF was evaporated off, water was added, the product extracted with chloroform, which was dried (Na2SO4), filtered and evaporated to give the N-p-chlorobenzyl-benzamide (2.07 g.) as a viscous oil, b.p. 240°-245° C./0.35 mm.Hg.
