Trimethyl orthoformate → 1,1-Dimethoxy-8-methylnon-2-yne

Participants

Reaction Steps

One gm. (0.007 mole) of 8-methylnon-2-yn-1-al, 10 gm. (0.1 mole) of trimethylorthoformate and 0.2 g of para-toluene-sulfuric acid were distilled. Methyl formate and methyl alcohol were collected. The solution was diluted with 15 ml of water and extracted with ether. The ether solution was washed with 5% sodium bicarbonate, and then water. The ether extract was dried over sodium sulfate, concentrate and distilled under vacuum to give 1,1-dimethoxy-8-methyl-non-2-yne.
