Chloromethyl Methyl Ether → HCID 86688864, compound

Participants

Reaction Steps

66 g of diisopropyl ethyl amine was dropped to a solution prepared by dissolving 100 g of 3-bicyclo[2.2.1]hept-5-en-2-yl-3-hydroxy-propionic acid tert-butyl ester (BHP) i and 44 g of chloromethyl methyl ether ii in 1 L of methylene chloride while stirring at room temperature. The mixture was stirred at room temperature for 4 hours, and reaction was evaluated by thin-layer chromatography (TLC) and terminated. This was followed by workup twice with 400 ml of each of a 1 N HCl solution and a 10% Na2CO3 solution, the resultant was washed with 400 ml of distilled water, and an organic layer was collected. Methylene chloride was removed from the organic layer at reduced pressure to obtain 96 g of 3-bicyclo[2,2,1]hept-5-en-2-yl-3-methoxymethoxy-propionic acid t-butyl ester iii (Yield: 81%). The structure was identified using 1H NMR.
