Grignardization of 1-butynyl magnesium bromide with acetaldehyde and subsequent treatment of the resulting alcohol with PCI5 yields 2-chloro-3-pentyne. Now, ethyl (l-methyl-2-pentynyl)-eyanoaeetate is obtained therefrom by its condensation with ethyl cyanoacetate in the presence of sodium ethylate. Further condensation of the resulting produet with allyl bromide gives rise to ethyl-(l-methyl-2-pentynyl) allylcyanoaeetate. Condensation with N-methyl urea and subsequent neutralization with NaOH produees methohexital sodium. [Pg.114]
