A mixture of (1-(5-(3,6-dihydro-2H-pyran-4-yl)-4-((1-(quinolin-2-yl)azetidin-3-yl)oxy)pyrimidin-2-yl)piperidin-4-yl)methanol (100 mg, 0.21 mmol) and wet Pd—C (50%, 50 mg) in MeOH (10 mL) was stirred under H2 (30 psi) at room temperature for 6 hours then the reaction mixture was filtered through CELITE® and washed with MeOH. The filtrate was concentrated in vacuo to give (1-(4-((1-(quinolin-2-yl)azetidin-3-yl)oxy)-5-(tetrahydro-2H-pyran-4-yl)pyrimidin-2-yl)piperidin-4-yl)methanol (90 mg, 0.19 mmol, yield 90%). ESI-MS (M+1): 476 calc. for C27H33N5O3 475. PDE10 IC50 (uM): 0.0029 1H NMR (CDCl3, 400 MHz) δ (ppm): 8.23 (d, J=9.2 Hz, 1H); 8.08-8.06 (m, 1H); 7.95-7.93 (m, 1H); 7.80-7.78 (m, 2H); 7.55-7.51 (m, 1H); 6.74-6.70 (m, 1H); 5.73-5.72 (m, 1H); 5.19-5.10 (m, 2H); 4.70-4.51 (m, 4H); 4.27 (d, J=6.4 Hz, 1H); 4.08-4.06 (m, 2H); 3.57-3.48 (m, 3H); 3.20-3.14 (m, 2H); 2.89-2.88 (m, 1H); 2.02-1.93 (m, 3H); 1.78-1.76 (m, 4H); 1.42-4.37 (m, 2H).
