Preparation of (R)-3-amino-1-(3-(pyridin-2-ylmethoxy)phenyl)propan-1-ol

[0443]

[0444](R)-3-amino-1-(3-(pyridin-2-ylmethoxy)phenyl)propan-1-ol was prepared following the method used in Example 4:

[0445]Step 1: Reaction between 2-(bromomethyl)pyridine and phenol (7, Intermediate I) following the method used in Example 4 gave after purification by flash chromatography (40% EtOAc:hexane) (R)-tert-butyl (3-hydroxy-3-(3-(pyridin-2-ylmethoxy)phenyl)propyl)carbamate as a pale yellow solid. Yield (0.26 g, 88%); 1H NMR (400 MHz, CDCl3): δ 8.59 (d, J=4.8 Hz, 1H), 7.71 (t, J=7.6, 1.6 Hz, 1H), 7.52 (d, J=7.6 Hz, 1H), 7.27-7.20 (m, 2H), 7.03 (s, 1H), 6.96 (d, J=10.4 Hz, 1H), 6.87 (d, J=5.6 Hz, 1H), 5.21 (s, 2H), 4.87 (bs, 1H), 4.73-4.70 (m, 1H), 3.50-3.48 (m, 1H), 3.21-3.11 (m, 1H), 1.84-1.61 (m, 2H), 1.45 (s, 9H); MS: m / z 359.26 [M+H]+.

Preparation of (1R)-3-amino-1-(3-((tetrahydro-2H-thiopyran-3-yl)methoxy)phenyl)propan-1-ol

[0447]

[0448](1R)-3-Amino-1-(3-((tetrahydro-2H-thiopyran-3-yl)methoxy)phenyl)propan-1-ol was prepared following the method below.

[0449]Step 1: K2CO3 (0.72 g, 5.24 mmol) and phenol (7, Intermediate I) (0.3 g, 1.05 mmol) were added to a solution of (tetrahydro-2H-thiopyran-3-yl)methyl 4-methylbenzenesulfonate (0.29 g, 1.10 mmol) in DMF (10 mL). The reaction mixture was heated at 100° C. under reflux overnight and then cooled. The reaction mixture was extracted with EtOAc, organic layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure. Purification by flash chromatography (EtOAc:hexane 10-40% gradient) gave tert-butyl ((3R)-3-hydroxy-3-(3-((tetrahydro-2H-thiopyran-3-yl)methoxy)phenyl)propyl)carbamate as a light green solid. Yield (0.21 g, 52%); 1H NMR (400 MHz, CDCl3): δ 7.24 (t, J=8.0 Hz, 1H), 6.91 (d, J=8.0 Hz, 2H), 6.78 (d, 1H), 4.87 (bs, 1H), 4.71 (bs, 1H), 3.84-3.80 (m, ...

Preparation of (R)-3-amino-1-(3-((tetrahydro-2H-thiopyran-4-yl)methoxy)phenyl)propan-1-ol

[0451]

[0452](R)-3-Amino-1-(3-((tetrahydro-2H-thiopyran-4-yl)methoxy)phenyl)propan-1-ol was prepared following the method used in Example 7:

[0453]Step 1: Pyridine (7.6 mL, 98.4 mmol) was added at 0° C. to a solution of (tetrahydro-2H-thiopyran-4-yl)methanol (1.3 g, 9.84 mmol) in CH2Cl2 (20 mL) followed by the addition of TsCl (2.0 g, 10.83 mmol). The reaction mixture was stirred at ambient temperature for 18 h, diluted with H2O (200 mL) and extracted with CH2Cl2 (200 mL). Drying over anhydrous Na2SO4 followed by concentration in vacuo gave (tetrahydro-2H-thiopyran-4-yl)methyl 4-methylbenzenesulfonate as an off white solid. The crude was carried forward to the next step without additional purification. Yield (0.75 g, 30%).

[0454]Step 2: Reaction between (tetrahydro-2H-thiopyran-4-yl)methyl 4-methylbenzenesulfonate and phenol (7, Intermediate I) following the method used in Example 7 gave after puri...
