Dimethylformamide → [4-Amino-7-(morpholin-4-ylmethyl)pyrrolo[2,1-f][1,2,4]triazin-6-yl]methanol

Participants

Reaction Steps

To a solution of DMF (50 mL) was added (4-aminopyrrolo[2,1-f][1,2,4]triazin-6-yl)methanol (550 mg, 3.35 mmol) and 4-methylenemorpholin-4-ium chloride (Eur. J. Med. Chem. 1989, 24, 379-384) (636 mg, 4.69 mmol). The solution was stirred at rt for 1 h and then the solvent was evaporated. The oil was triturated with CH2Cl2 and a white solid was collected. The free based was obtained by stirring over a Dowex 66 solid support resin in MeOH. The material was filtered and evaporated yielding 794 mg (90%) of the desired product as a white solid. MS [M+H]+=264; LCMS RT=1.07.
