Participants

Reaction Steps

To a 20 mL vial charged with Sodium hydride (0.196 g, 7.76 mmol) was added dry N,N-Dimethylformamide (5.0 mL, 64 mmol), cooled with ice bath. N-(4-bromopyridin-2-yl)acetamide (1.50 g, 7.00 mmol) was added portionwise in ˜3 min. The suspension was stirred at the same temperature for 15 min and turned into a clear solution. 4-methoxybenzyl bromide (1.55 g, 7.70 mmol) was added dropwise with a syringe and rinsed down with dry N,N-Dimethylformamide (2.0 mL, 26 mmol). The mixture was stirred at r.t. for 17 hours. The mixture was poured into ice chilled saturated NaHCO3 (80 mL), extracted with EtOAc (2×100 mL), washed with water, brine, dried over anhydrous Na2SO4, filtered, evaporated in rotavpor to give a crude. Chromatograph using EtOAc/hexane (1/9 to 7/3) gave an oily product (1.80 g, yield 76.7%). LCMS: (AA) ES+, 335, 337. 1H NMR (400 MHz, d1-chloroform) δ: 8.28-8.30 (d, J=5.27 Hz, 1H), 7.43 (s, 1H), 7.31-7.33 (dd, J=5.52, 1.51 Hz, 1H), 7.13-7.15 (d, J=8.78 Hz, 2H), 6.80-6.82 (d, J=8.78 Hz, 2H), 5.05 (s, 2H), 3.77 (s, 3H), 2.12 (s, 3H).
