New approach to the synthesis of 2-alkylsulfanyl-4,5,6-trimethylnicotinonitriles
摘要:
Multicomponent condensation of acetaldehyde, cyanothioacetamide, 1-(but-2-en-2-yl)pyrrolidine, and alkyl halides afforded 2-alkylsulfanyl-4,5,6-trimethylnicotinonitriles. Their structure was confirmed by IR, H-1 NMR spectroscopy, and chromatography-mass spectrometry.
The present invention is directed to solid oral dosage forms comprising surface-treated particles comprising modafinil particles and a hydrophilic treating agent, methods of making the same, and uses thereof.
