To a stirred solution of 7-azaindole (1.18 g, 10.0 mmol) in anhydrous dimethylformamide (10 mL) cooled to 0° C. was added NaH [60% dispersion in mineral oil](0.480 g, 12.0 mmol) in portions over 15 min. The resulting mixture was allowed to stir for 1 hr at 0° C., after which (2-(chloromethoxy)ethyl)trimethylsilane [SEM-Cl] (2.12 mL, 12.0 mmol) was added over 15 min. The resulting mixture was stirred for 1 hr, after which it was quenched with H2O (50 mL), and partioned between EtOAc and H2O. The organic layer was separated, washed with brine, dried over MgSO4, filtered, and evaporated in vacuo to yield a yellow oil (2.50 g, 100%). HPLC retention time: 2.66 minutes; MS ESI (m/z): 249.4 (M+1)+, calc. 248.
