Sodium hydride → HCID 57678299, compound

Participants

Reaction Steps

A solution of 1H-imidazole-4-carbaldehyde (1.92 g, 20 mmol) in anhydrous THF (32 mL) and DMF (8 mL) was treated with sodium hydride (60% dispersion in mineral oil, 880 mg, 22 mmol) for 5 mins. 2-Bromoacetamide (3.59 g, 26 mmol) was added and the reaction was stirred continuously overnight. The THF was concentrated, loaded on a silica column, and eluted with 20% methanol in dichloromethane. The solvent was evaporated to yield 2.70 g of the product as a white solid (88.2%). HPLC Method D, r.t.=1.5 min, (96.4% purity at 256 nm). LC/MS calculated mass=153.14, [M−H]−=152, [M+H]+=154.
