Participants

Reaction Steps

10 g of ethyl magnesium bromide was added over 30 minutes to a stirred solution of 10.2 g of 1A in 100 ml of tetrahydrofuran at 0° C. The resulting mixture was stirred at that temperature for 30 minutes, then a solution of 7.75 g of trimethylsilyl chloride in 30 ml of tetrahydrofuran was added over 30 minutes. The mixture then was stirred at 0° C. for 90 minutes, treated with brine, dried (MgSO4) and the solvent was evaporated. The residue was distilled at 85°-90° C., 0.3 Torr., to give N-benzylidene-3-(trimethylsilyl)-2-propyn-1-amine (1B), as a water-white oil.
