Методика
U.S. Pat. No. 4,927,855 describes the preparation of the levorotatory enantiomer of modafinil by chiral resolution of the 2-[(diphenylmethyl)sulfinyl]acetic acid with α-methylbenzyl amine. After recovery and amidation of the enantiomerically pure acid, (−) modafinil was obtained as white crystals by crystallization from ethanol.
