实验过程

To a solution of 2-chloro-7-(4-fluorophenyl)-N-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (Preparation Hh) (141.2 mg, 0.508 mmol) and 3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)aniline (Preparation D) (208 mg, 1.017 mmol) in N-Methyl-2-pyrrolidinone (4067 μL) was added H2SO4 (43.4 μL, 0.813 mmol). The solution was heated to 100° C. When the reaction was complete, water and NaHCO3 were added. After extraction into CH2Cl2, the organic extracts were dried over MgSO4, filtered, and concentrated in vacuo. Applied the residue to SG and eluted with a EtOAc/Hex gradient, which yielded 7-(4-fluorophenyl)-N2-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)-N4-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidine-2,4-diamine (Example 44).
