Reaction Steps

4-((R)-5-cyclopentyl-4-ethyl-4,5-dihydro-[1,2,4]triazolo[4,3-f]pteridin-7-ylamino)-3-chlorobenzoic acid (1-3) (27 mg) was dissolved in DMF (0.4 ml) and treated with carbonyl diimidazole (12 mg, 0.077 mmol) and the mixture stirred at RT for 90 min. The solution was cooled in an ice bath and methylamine gas bubbled in for 2 min. The mixture was stirred at RT for 2 hours, evaporated under reduced pressure and purified by chromatography to give 4-((R)-5-cyclopentyl-4-ethyl-4,5-dihydro-[1,2,4]triazolo[4,3-f]pteridin-7-ylamino)-3-chloro-N-methylbenzamide (15 mg) as a colourless solid.
