Participants

Reaction Steps

Ethyl (2R, 3S)-3-hydroxy-2-methylbutyrate (8.20 g) and methyl iodate (78.0 g) were dissolved in N,N-dimethylformamide (150 ml). To this solution was added sodium hydride (about 60% in oil, 2.46 g) little by little with ice cooling and the mixture was stirred for 1 hour with ice cooling. The reaction mixture was poured into ethyl acetate (300 ml) and the mixture was stirred for 10 minutes. Insoluble materials were filtered off and the filtrate was washed 3 times with water. The organic layer was dried, concentrated and distilled under reduced pressure (b.p. 80° C./30 mmHg) to obtain ethyl (2R, 3S)-3-methoxy-2-methylbutyrate (6.87 g).
