実験手順

1-(1-(3-((1-(quinolin-2-yl)azetidin-3-yl)oxy)pyridazin-4-yl)piperidin-4-yl)ethanone (100 mg, 0.25 mmol) was dissolved in 10 ml of methanol. This solution was cooled down to 0° C. using an ice bath and sodium tetraborohydride (19 mg, 0.50 mmol) was added by portions. The reaction mixture was stirred for 4 hours at ambient temperature, and then saturated aqueous solution of ammonium chloride (5 mL) was added. The methanol was evaporated off under reduced pressure then the reaction mixture was taken up in ethyl acetate. The organic layer was separated from the aqueous layer. The aqueous layer was back extracted one more time with ethyl acetate. The organic layers were combined and dried over magnesium sulfate, followed by concentration under reduced pressure. The residue was purified by column chromatography on silica gel to give (racemic mixture) 1-(1-(3-((1-(quinolin-2-yl)azetidin-3-yl)oxy)pyridazin-4-yl)piperidin-4-yl)ethanol (76 mg, 0.19 mmol, 75% yield). ESI-MS (M+1): 406 calc. for C23H22N5O2 405. PDE10 IC50 (uM): 0.0767. 1HNMR (CD3OD, 400 MHz) δ (ppm): δ (ppm) 8.40 (m, 1H); 8.14-8.10 (d, J=8.8 Hz, 1H); 7.97 (d, J=8.8 Hz, 1H); 7.64-7.58 (m, 2H); 7.51-7.46 (m, 1H); 7.20-7.16 (m, 1H); 6.80-6.79 (m, 1H); 6.62 (d, J=9.2 Hz, 1H); 5.62-5.59 (m, 1H); 4.61-4.57 (m, 2H); 4.18-4.15 (m, 2H); 3.96-3.93 (m, 2H); 3.48-3.43 (m, 1H); 2.73-2.67 (m, 2H); 1.91-1.88 (m, 1H); 1.66-1.64 (m, 1H); 1.42-1.34 (m, 3H); 1.11-1.10 (d, 3H).
