実験手順

3-Phenyl-1H-pyrazolo[4,3-c]pyridine (2.93 g) was suspended in 30 ml of N,N-dimethylformamide to which 1-(2-chloroethyl)imidazole (2.15 g) and K2CO3 (2.3 g) had been added. This mixture was stirred and warmed at 90° for 2 hours and then an additional 0.20 g of 1-(2-chloroethyl)imidazole and 0.2 g of K2CO3 were added. After an additional 45 minutes, the reaction mixture distributed between H2O and ethyl acetate and the organic phase was washed with water. Evaporation and trituration with ether gave 2.15 g of product after recrystallization from CH2Cl2 -pentane, mp 123°-125°.
