Reaction Steps

(S)-1-(1,5-dimethylhexyl)-3-[7-(4-hydroxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl]urea (the compound obtained in Example 255; 30 mg) and potassium carbonate (108 mg) were suspended in methyl ethyl ketone (3 ml). Thereafter, 2-methoxyethyl bromide (327 mg) was added to the obtained suspension, and the obtained mixture was stirred at 80° C. for 10 hours. Thereafter, the reaction solution was cooled to a room temperature, and methylene chloride (5 ml) was then added thereto. The obtained mixture was washed with an aqueous 1 M hydrochloric acid solution (5 ml×3), an aqueous saturated sodium bicarbonate solution (5 ml×2), and distilled water (5 ml×2). The organic layer was concentrated under a reduced pressure, and the obtained residue was purified by reverse phase liquid chromatography (Inertsil PREP-ODS; 20 Φ×250 mm; eluted with water-containing acetonitrile) to obtain the captioned compound (14 mg).
