Participants

Reaction Steps

Into a solution of the acetamide (640 mg, 1.76 mmol) in a mixed solvent (10 ml) of methanol and acetonitrile (1:4) were dropped N,N-diisopropylethylamine (0.43 ml, 2.46 mmol) and trimethylsilyl diazomethane (1.23 ml, 2.46 mmol) and the mixture was stirred for 12 hours. The residue obtained by evaporation of the solvent was made alkaline by adding 2N sodium hydroxide and then extracted with chloroform. The organic layer was washed with water and a saturated sodium chloride solution successively and dried over anhydrous sodium sulfate and the solvent was evaporated therefrom to provide 550 mg (yield 83%) of 2-[4-(2-hydroxyethyl)piperazin-1-yl]-N-(2,6-diisopropyl-4-methoxyphenyl)acetamide as colorless crystals.
