Procedure

5-tert-Butyl-N-(2-(2-tert-butylphenoxy)pyridine-3-yl)-1H-benzo[d]imidazol-2-amine (Example 6, 50 mg, 0.121 mmol) was dissolved in THF (2 mL). At 0° C., NaH (2.6 mg, 0.109 mmol) was added and the mixture stirred for 10 min. ICH3 (15 mg, 0.109 mmol) was then slowly introduced. The solution turned purple. After 15 min additional stirring, the solvent was removed under vacuum and the crude product was purified by column chromatography on silica gel (eluting with a continuous gradient of MeOH from 0% to 5% in CH2Cl2). tR=6.265 min (Shimadzu Phenomenex S5 ODS 4.6×50 mm Luna 4.6×50 mm; flow rate 2.5 mL/mn; detection at 220 nM; Gradient elution 0% to 100% B over 8 min; (A=10% MeOH, 90% H2O, 0.2% H3PO4 & B=90% MeOH, 10% H2O, 0.2% H3PO4). HRMS (ESI) m/z calcd for C27H32N4O [M+H]+429.2654, found 429.2636.
