반응 단계
The (−)-α-methylbenzylamine-(−)-benzhydrylsulphinyl acetate is then converted to (−)-benzhydrylsulphinylacetic acid by acid hydrolysis. The latter is esterified in the presence of dimethyl sulphate and then converted to amide in the presence of ammonia (gas). The (−) or l (laevorotatory) enantiomer of modafinil is obtained through this process with an overall yield of 5.7% in relation to the (±) modafinil acid, calculated on the basis of the yields corresponding to each stage.
