Versuchsvorschrift

A THF (2 ml) suspension of sodium hydride (0.06 g, 60% oil suspension, 18.78 mmol) was cooled in an ice bath, and a THF (2 ml) solution of 3-cyclopropyl-3-oxopropanenitrile was dripped thereto. To the obtained reaction solution, a THF (3 ml) solution of 2-methyl-6-(1H-1,2,4-triazol-1-yl)nicotinic acid chloride (0.16 g, 0.73 mmol) was dripped. The resultant was stirred at room temperature for 3 hours. The obtained reaction solution was made acidic with a citric acid aqueous solution, and the product was extracted with ethyl acetate. The obtained organic layer was washed with water, dried with magnesium sulfate and concentrated to obtain the desired product (0.14 g, yield 64%).
