Dimethylformamide → 3-Methoxy-2-(methoxymethyl)propan-1-ol

Participants

Reaction Steps

Sodium hydride (60% dispersion in oil) (2.93 g, 73.2 mmol) was added to an ice-cooled solution of 2-hydroxymethyl-propane-1,3-diol (M. R. Harnden et al. J. Med. Chem. 1990, 33, 187) (3.53 g, 33.3 mmol) in DMF (100 ml) and the mixture was stirred at room temperature for 40 min. The reaction mixture was cooled with ice and iodomethane (4.56 ml, 73.2 mmol) was added, the stirring was continued allowing the mixture to reach room temperature over 24 h. The mixture was poured into ethyl acetate (300 ml) and washed with brine (150 ml). The organic phase was dried (MgSO4), and the solvent was evaporated. The crude product was purified by flash column chromatography (silica, ethyl acetate) to afford colourless oil. 1H NMR (300 MHz, CDCl3) 3.72 (2H, d), 3.47 (2H, d), 3.45 (2H, d), 3.32 (6H, s), 2.07(1H, m).
