実験手順

10 g (38.9 mmoles) of 2-[(diphenylmethyl)thio]acetamide are dissolved in 100 ml of dichloromethane. The solution is added with 15.7 g of 68% w/w ε-phthalimidoperhexanoic acid, keeping the temperature at about 20° C., and after 6 h is diluted with water, adjusting the pH to 8–9 with aqueous ammonia. The resulting phases are separated and the organic one is evaporated to dryness, to obtain 8.5 g of 2-[(diphenylmethyl)sulfinyl]acetamide (modafinil). Molar yield: 80%.
