실험 절차

2-Amino-3-cyano-4-methyl-5-(3-pyridyl)pyrrole (compound No. 8) obtained in the same manner as Example 1 (5.0 g) was dissolved in methanol (220 ml) under heating, followed by addition of 40% HCl-methanol (4 ml) under ice-cooling with stirring. The separated crystals were collected by filtration, washed with methanol (50 ml) twice and diethyl ether (50 ml) 3 times, and air-dried. The crude crystals thus obtained were recrystallized from methanol to provide the title compound as reddish brown crystals (3.4 g). m.p. 279-281° C.
