Procedure

A mixture of ethyl 2-methyl-2-(4-((9-methyl-2-(2-methyl-1H-benzo[d]imidazol-1-yl)-6-morpholino-9H-purin-8-yl)methyl)piperazin-1-yl)propanoate 507 (0.14 g, 0.25 mmol) in 2M LiOH (5.0 mL) and THF (8 mL) was stirred at reflux for 18 hours. The reaction was then cooled to room temperature and concentrated down to ⅓ of original volume. The residue was then loaded onto a SCX-2 column. The column was first washed with MeOH. The product was then eluted with 2M NH3 in MeOH and then concentrated. The residue was purified by RP-HPLC to give 506. LCMS m/z: 534.3 (MH+)
