実験手順

1 Benzyloxymethyl-1-methylethane-1,2-diol (2g) in dimethyl formamide (25 ml) was treated with a slight excess of sodium hydride (0.6g) at ambient temperature for 1h, then 90° for 15 mins. The product was then treated with benzyl chloride (4g) and 1,2,3-tribenzyloxy-2-methylpropane was isolated by evaporation of the solvent followed by chromatography on silica gel eluted with 9/1 methylene chloride/ether. The desired product was a colourless oil whose structure was confirmed by n.m.r.
