1-(2-Chloro-ethyl)-3-naphthalen-2-yl-urea (I-79a: 750 mg, 3.01 mmol) in dry DMF (10 mL) was added to a stirred solution of sodium hydride (150 mg, 3.1 mmol) in THF (10 mL) at 0° C. The reaction temperature was maintained at room temperature for 30 minutes. The reaction was monitored by TLC (5% MeOH in chloroform, double run). The reaction mixture was quenched with MeOH at 0° C., concentrated under reduced pressure and partitioned between ice water and chloroform. The organic layer was dried over Na2SO4, and concentrated under reduced pressure to afford 600 mg (94% yield) of 1-naphthalen-2-yl-imidazolidin-2-one.
