Conditions
- Temperature
- 80 °C
Procedure
2-[(S)-1-Phenylethylamino]-4-[5-hydroxybenzimidazol-1-yl]-pyrimidine (25 mg) was dissolved in DMF (2.0 mL) and NaH (60%, 6.0 mg) was added followed by N-benzyloxycarbonyl-2-(methanesulfonyloxy)methylpyrrolidine (20 mg) and the resulting suspension was heated to 80° C. for 1 hour. After cooling to room temperature, the solution was then diluted with 10 mL of aqueous saturated NaHCO3 and extracted with 2×10 mL of of EtOAc. The combined organic extracts were then dried (MgSO4) and concentrated under reduced pressure. The residue was purified with preparative thin-layer chromatography (SiO2, 5% MeOH in CH2Cl2) to yield 17 mg of 2-[(S)-1-Phenylethylamino]-4-[5-((N-benzyloxycarbonyl-pyrrolidin-2-yl)methoxy)benzimidazol-1-yl]pyrimidine. Mass spectrum (ESI) 549.3 (M+1).
