A mixture of acetic acid 1,1-dimethyl-2-{3-[9-methyl-2-(2-methylbenzoimidazol-1-yl)-6-morpholin-4-yl-9H-purin-8-ylmethyl]azetidin-1-yl}-2-oxoethyl ester (125 mg, 0.23 mmol) and LiOH (114 μL, 0.46 mmol, 4M solution) in THF (3 mL) and MeOH (1 mL) was allowed to stir at r.t. for 18 h. Further LiOH (343 μL, 1.37 mmol, 4M solution) and the mixture stirred at 50° C. for 5 days. The reaction mixture was concentrated in vacuo and the resulting residue loaded onto an Isolute® SCX-2 cartridge which was washed with MeOH and the product eluted with 2M NH3/MeOH. The resulting residue was purified by column chromatography (Si-PCC, MeOH:EtOAc, 0-10%) then dissolved in a mixture of MeCN and H2O and allowed to freeze-dry affording 855 as a white solid (88 mg, 77%).
