Procedure

(S)-1-[7-(4-benzyloxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl]-3-(1,5-dimethylhexyl)urea (the compound obtained in Example 245; 7.1 g) and palladium carbon (50% water content; 2.0 g) were suspended in acetic acid (570 ml), and the obtained suspension was stirred in a hydrogen atmosphere at a room temperature for 5 days. Thereafter, the reaction solution was filtrated with a filter medium (Celite), and the collected product was then washed with methanol. The filtrate and the washing solution were mixed, and the obtained mixture was then concentrated under a reduced pressure. The obtained residue was dissolved in methylene chloride (150 ml), and the obtained solution was washed with a saturated saline solution (100 ml) twice. The saturated saline solution layer obtained after the second washing was extracted with methylene chloride (70 ml×3). The organic layers were gathered, and the obtained layer was then concentrated under a reduced pressure. The obtained residue was purified by silica gel column chromatography (eluted with 1% to 2% methanol-containing methylene chloride) to obtain the captioned compound (4.72 g).
