Reaction Steps

To a solution of 2-amino-2-benzylhexane-1-ol intermediate II (0.100 mg, 0.48 mmol) in 1.1 mL DMF cooled to 0° C. was added sodium hexamethyldisylazide (0.48 mL, 0.48 mmol, 1 M in THF). The reaction mixture was stirred at 0° C. for 5 min and intermediate A 3-(bromomethyl)-N-[(1R)-1-(4-fluorophenyl)ethyl]-5-[methyl(methylsulfonyl)amino]benzamide (0.040 g, 0.090 mmol) in 1.8 mL DMF was added dropwise. The reaction mixture was stirred at 0° C. for 1.5 h, and quenched by adding water. The aqueous layer was washed with EtOAc (3×), and the combined organics were washed with brine, dried over Na2SO4, filtered and concentrated. Purification by silica gel chromatography (20 g silica, 0->8% 0.1% NH4OH in i-PrOH/hexanes) afforded 3-{[(2-amino-2-benzylhexyl)oxy]methyl}-N-[(1R)-1-(4-fluorophenyl)ethyl]-5-[methyl(methyl sulfonyl)amino]benzamide. 1H NMR (400 MHz, CDCl3) δ 7.73 (s, 1H), 7.69 (s, 1H), 7.53 (s, 1H), 7.37-7.34 (m, 2H), 7.29-7.20 (m, 3H), 7.17-7.15 (m, 2H), 7.04 (m, 2H), 6.56 (br s, 1H), 5.30 (m, 1H), 4.56 (s, 2H), 3.34 (s, 3H), 3.20 (m, 2H), 1.59 (d, J=6.9 Hz, 3H), 1.60-1.39 (br m, 6H), 0.90 (t, J=7.0 Hz, 3H).
