Procedure
(S)-1-[7-(4-hydroxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl]-3-[1-(3-methoxyphenyl)ethyl]urea (the compound obtained in Example 223; 20.3 mg) was suspended in 2-butanone (2 ml). Thereafter, potassium carbonate (69.4 mg) and 2-methoxyethyl bromide (47.2 μl) were added to the suspension, and the obtained mixture was stirred at 80° C. for 5 hours. Thereafter, the reaction solution was diluted with methylene chloride (5 ml), and the resultant product was then washed with 1 M hydrochloric acid (5 ml×3), saturated sodium bicarbonate (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 (10.7 mg).
