Participants

Reaction Steps

A mixture of 6-benzyl-5,6,7,8-tetrahydro-N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)pyrido[3,4-d]pyrimidin-4-amine (0.742 g, 1.98 mmol), ammonium formate (1.25 g, 19.83 mmol) and palladium; 10% wt. on activated carbon (75 mg) in methanol (10 mL) is heated to 60° C. for 2 h. The mixture is cooled to r.t. and filtered over celite. The filtrate is concentrated under reduced pressure to give a white solid which is dissolved in water. The mixture is extracted twice with a 3:1 mixture of chloroform: isoproanol. The combined organic extracts are dried over sodium sulfate and concentrated to dryness to give the title compound.
