- Molecular formula:C9H11N3
- Molecular Weight:161.2
Yield:127680-78-8 30.8%
Reaction Conditions:
at 90; for 48 h;Sealed tube;
Steps:
18.1
Step 1: 2-(Isopropylamino)isonicotinonitrile (90). A mixture of 56 (4.5 g, 32.4 mmol) and isopropylamine (20 mL, 327 mmol) was heated at 90° C. for 48 h in a sealed tube. The reaction mixture was concentrated in vacuo, water was added to the residue and resulting aqueous mixture was extracted with EtOAc, dried over Na2SO4, concentrated and purified by column chromatography to afford 90 (1.6 g, 30.8%).
