Reaction Steps

The mixture of N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-7-phenyl-4-(1,4-dioxa-7-azaspiro[4.4]nonan-7-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-2-amine (Example 205) (37 mg, 0.068 mmol) and HCl (272 μL, 0.272 mmol) in THF (339 μL) was heated at 60° C. overnight. Concentrated to remove THF and added Acetone (339 μL) and HCl (272 μL, 0.272 mmol) to the mixture. The mixture was heated at 60° C. for 6 h. The crude product was purified by Prep-HPLC (Solvent A=10% MeOH-90% H2O-0.1% TFA, Solvent B=90% MeOH-10% H2O-0.1% TFA. Column. PHENOMENEX LUNA 30×100 mm, S10, Flow rate: 40 ml/min, 35-100% B, 40 min) and then was purified by Prep-HPLC (Column: PHENOMENEX LUNA C18 30×100 mm, Solvent A=10 mM Ammonium Acetate in 95:5 H2O/ACN, Solvent B=10 mM Ammonium Acetate in 5:95 H2O/ACN. Flow rate: 40 ml/min, 30-100% B, 35 min) to get 1-(2-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenylamino)-7-phenyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)pyrrolidin-3-one (2.0 mg, 3.59 μmol, 5.29% yield).
