Participants

Reaction Steps

A solution of 6-aminonicotinonitrile (100.0 mg, 0.839 mmol) and 4-methyldihydro-2H-pyran-2,6(3H)-dione (118 mg, 0.923 mmol) in a mixed solvent of toluene (3 mL) and DMSO (0.3 mL) was stirred at 120° C. for 24 hr. To the reaction mixture was added cold water, and the mixture was extracted with ethyl acetate (4×30 mL). The organic layer was washed with water, and dried, and the solvent was evaporated under reduced pressure. The obtained solid was washed with 50% dichloromethane/hexane solution to give 4-(5-cyanopyridin-2-ylcarbamoyl)-3-methylbutyric acid (30 mg, 14.49%) as a pale-yellow powder.
