Participants

Reaction Steps

To a solution of 0.432 g (1 mmol) of diphenylmethyl ester obtained in Example 91 in THF (5 ml) was added under ice-cooling, 88 mg (2.2 mmol) of sodium hydride (60% dispersion in mineral oil). The mixture was stirred for 30 minutes at room temperature. Subsequently, to the mixture was added 110 μl (1.2 mmol) of dimethylcarbamoyl chloride under ice-cooling and stirred for 1 hour at room temperature. The reaction mixture was poured into aqueous ammonium chloride and extracted with ethyl acetate. The extract was washed with water and dried. The solvent was removed and the residue was crystallized from ether. The crystal was collected by filtration and washed with ether to give 0.39 g of the titled compound. Yield: 77%.
