Participants

Reaction Steps

To a solution of 1,1-dimethyl-3-[2-[2-(1-piperidinyl)ethyl]phenyl]-1,3-propanediamine (2.1g) in 50 ml of 2-propanol is added 2.0g of oxalic acid in 25 ml of 2-propanol. The precipitate that forms is filtered, dissolved in 20 ml of methanol, and 40 ml of chloroform is added. The solution is then concentrated to 50 ml and the solution cooled; a fine crystalline mass is deposited. Recrystallization from methanol-chloroform (1:2) yields the title compound, melting point 101°-102° C.
