Reaction Steps

20 mg of (S)-{2-[1-(4-fluorophenyl)ethylamino]-6-(pyrazin-2-ylamino)pyridin-4-yl}methanol (Example 140) was dissolved in methylene chloride, and 59 mg of carbon tetrabromide and 47 mg of triphenylphosphine were added under ice-cooling, and the mixture was stirred for 30 minutes. Subsequently, 90 μl of 9.8M sodium methoxide/methanol solution was added thereto, and the mixture was stirred overnight. The reaction solution was diluted with ethyl acetate and was washed in turn with water and brine and then dried over magnesium sulfate. The solvent was distilled of f under reduced pressure, and then the obtained residue was purified by silica gel column chromatography to obtain 7 mg of the objective compound as yellow powder.
