Procedure

To a solution of 3-[2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purin-8-yl]-3-hydroxyazetidine-1-carboxylic acid tert-butyl ester (620 mg, 1.16 mmol) in DCM (5 mL) was added TFA (2 mL) and the resulting mixture allowed to stir for 1.5 h at r.t. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge which was washed with DCM and MeOH and the product eluted with 2M NH3/MeOH affording 3-[2-(2-Ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purin-8-yl]azetidine-3-ol as a yellow oil (450 mg, 89%). LCMS: (method A): RT 1.84 min [M+H]+ 435.2
