[0207] (R)-5-(4-(3(3,5-difluoro-4-(4-methyl-4,5-dihydro Azol-2-yl)phenoxy)propyl)piperidin-1-yl)-3-isopropyl-1,2,4- Preparation of oxadiazole
[0208] (Step 1-1) Preparation of 4-(3-hydroxypropyl)piperidine-1-carbonitrile (chemical formula 3)
[0209]
[0210] 3-(piperidin-4-yl)propan-1-ol hydrochloride (10g, 69.8mmol) of chemical formula 2 was dissolved in a mixed solution of dichloromethane (MC, 75.0ml) and water (55.0ml); Sodium bicarbonate (NaHCO 3 , 16.36g, 195.0mmol) was added thereto; then cyanogen bromide (6.48g, 61.2mmol) was added thereto; stirred at room temperature for 15 hours. An excess of aqueous ammonium chloride was added thereto; extracted with dichloromethane; then washed with brine. with MgSO 4 Moisture was removed from the organic layer, which was then filtered and concentrated under reduced pressure to obtain the desired form of compound 4-(3-hydroxypropyl)piperidine-1-carbonitrile in quantitative yield, which was used in the next step reactio...

[0240] 3-(2,6-difluoro-4-(3-(1-(5-(5-isobutyl-1,2,4- Oxadiazol-3-yl)pyrimidin-2-yl)piperidin-4-yl)propoxy)phenyl)-5-methyl-1,2,4- Preparation of oxadiazole
[0241] (Step 2-1) Preparation of 3-(1-(5-bromopyrimidin-2-yl)piperidin-4-yl)propan-1-ol
[0242]
[0243] 3-(piperidin-4-yl)propan-1-ol (10g, 69.8mmol) and 5-bromo-2-chloropyrimidine (13.5g, 69.8mmol) of chemical formula 2 were dissolved in N,N-dimethyl Formamide (DMF, 10ml), then potassium carbonate (K 2 CO 3 , 10.6g, 76.8mmol) was added thereto, and the reaction was carried out at 80°C for 12 hours. The reaction solution was cooled to room temperature, diluted with water, extracted with ethyl acetate (EA, 150ml), and washed with brine. with MgSO 4 Water was removed from the organic layer, which was filtered and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the desired form of compound 3-(1-(5-bromopyrimidin-2-yl)piperidin-4-yl)propan-1-ol in 82% ...
