Phosphorus tribromide → 4-(8-(bromomethyl)-9-methyl-2-(2-methyl-1H-benzo[d]imidazol-1-yl)-9H-purin-6-yl)morpholine

Participants

Reaction Steps

To crude (9-methyl-2-(2-methyl-1H-benzo[d]imidazol-1-yl)-6-morpholino-9H-purin-8-yl)methanol (6 g) in anhydrous THF (400 mL) was added phosphorus tribromide (2.7 mL). The reaction was monitored by LC/MS until complete. The heterogeneous reaction mixture was passed thru a Buchner funnel and the solid was collected and rinsed with thrice with water and twice with MeOH.to get 2 g of crude 4-(8-(bromomethyl)-9-methyl-2-(2-methyl-1H-benzo[d]imidazol-1-yl)-9H-purin-6-yl)morpholine of which 50 mg was reacted with bicyclo[2.2.2]octan-1-amine (1-adamantyl amine) via General Procedure E to give 5.7 mg of 270 following reverse phase purification.
