Participants

Reaction Steps

To a solution of 7-bromomethyl-8-propyl-[1,2,4]triazolo[1,5-c]pyrimidine (16.58 mmol) in CH3CN (30 ml) is added K2CO3 (9.15 g, 66.3 mmol), isobutylamine (6.6 ml, 66.3 mmol) and the mixture is stirred at room temperature overnight. The solvent is removed in vacuo and to the residue is added water (60 ml) and EtOAc (60 ml). The layers are separated and the organic layer is washed with brine (20 ml) and dried (Na2SO4). Evaporation of the solvent provides a light yellow oil, which is used in next step without further purification.
