Reaction Steps

In a 20 mL vial was added N-(4-(piperidin-4-yl)phenyl)-3-(pyridin-3-yl)azetidine-1-carboxamide, bistrifluoroacetic acid (67 mg, 0.12 mmol) dissolved in methanol, (2.0 mL) followed by the addition of cyclopentanecarbaldehyde (13 mg, 0.13 mmol) dissolved in methanol (0.45 mL), followed by the addition of acetic acid neat (68 μL, 1.2 mmol). The reaction mixture was shaken for 1 hour at 70° C. After that, MP-cyanoborohydride (272 mg, 2-3 mmol/g) resin was added and the resulting mixture was shaken at 70° C. overnight. The reaction mixture was filtered and concentrated to dryness. The residues were dissolved in 1:1 DMSO/methanol and purified by reverse phase chromoatography. 1H NMR (500 MHz, pyridine/d5-D2O Temp=90° C.) δ ppm 8.55 (dd, J=4.73, 1.68 Hz, 1 H) 8.40-8.48 (m, 1 H) 7.75 (d, J=8.54 Hz, 2 H) 7.56-7.61 (m, 1 H) 7.21 (d, J=8.54 Hz, 2 H) 7.16-7.19 (m, 1 H) 4.46 (t, J=8.24 Hz, 2 H) 4.10 (dd, J=8.09, 5.95 Hz, 2 H) 3.64-3.74 (m, 1 H) 3.28 (d, 2 H) 2.39-2.66 (m, 5 H) 2.02-2.26 (m, 3 H) 1.75-1.88 (m, 4 H) 1.40-1.59 (m, 4 H) 1.20-1.31 (m, 2 H); (ESI) m/z 419 (M+H).
