Methyl iodide → 5-[2-(2-Chloro-4-methoxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-1-methyl-1H-pyridin-2-one

Participants

Reaction Steps

To a solution of 5-[2-(2-chloro-4-methoxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-1H-pyridin-2-one (Example 194, 100 mg) in N,N-dimethylacetamide (1.5 ml) were added powdered K2CO3 (42 mg) and iodomethane (41 mg). The mixture was stirred at room temperature for 3 days. EtOAc and water were added and the mixture was extracted with EtOAc. The organic phase was dried (MgSO4), filtered and concentrated to dryness. The product was purified by chromatography (SiO2, cyclohexane/EtOAc 1:1=>0:1) to give the title compound (113 mg, contains 10.7 mass-% of N,N-dimethylacetamide) as a light yellow oil. MS (m/e)=376.1 [M+H+].
