実験手順
To a stirred solution of 0.50 moles of propargylmagnesium bromide in 340 ml. of ether at -78° C. is added a solution of 65.2 g. (0.50 moles) of the ethyl valerate in 100 ml. of ether during 60 minutes. The solution is stirred at -78° C. for 30 minutes and then hydrolyzed by pouring onto a mixture of ice and ether. The ether layer is washed with brine, treated with hydroquinone, dried over magnesium sulfate, and concentrated.
