Participants

Reaction Steps

To a solution of 7-(2,4-dichloro-phenyl)-2-methyl-2H-pyrazolo[3,4-c]pyridine (0.029 g, 0.10 mmol) in 1 mL of diethyl ether was added 0.100 mL of a 2 M solution of HCl in ether. The resulting white suspension was stirred for 15 m then concentrated to afford 0.031 g of 7-(2,4-dichloro-phenyl)-2-methyl-2H-pyrazolo[3,4-c]pyridine hydrochloride (32 HCl) as an off-white solid: m.p. 191-196.
