Reaction Steps

A solution of 205.6 mg (1.49 mmol) 4-aminomethyl-pyridine-2,6-diamine in 5 ml pyridine was treated with 198 mg (1.49 mmol) cyclopentane carboxylic acid chloride and a catalytic amount 4-dimethylaminopyridine and stirred for 2.5 h at room temperature. The mixture was evaporated to dryness and the residue was purified by column chromatography on silica eluting with dichloromethane/methanol 9/1 to yield 93 mg (26%) of the title compound.
