Acetone → 1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole-4-carbonitrile

Participants

Reaction Steps

A flask charged with imidazole-4-carbonitrile (0.50 g, 5.2 mmol) (Synthesis, 677 (2003)) 2-(trimethylsilyl)ethoxymethyl chloride (SEMCl) (0.95 mL, 5.3 mmol), K2CO3 (1.40 g, 10.4 mmol), and acetone (5 mL) was stirred for 10 h at RT. The mixture was diluted with EtOAc (20 mL) and washed with water (20 mL) and brine (20 mL) and the organic layer dried over MgSO4. The crude product was eluted from a 20-g SPE cartridge (silica) with 30% EtOAc/hexane to give 0.80 g (70%) of the title compound as a colorless oil. Mass spectrum (CI(CH4), m/z) Calcd. for C10H17N3OSi, 224.1 (M+H), found 224.1.
