Reaction Conditions

Reaction Steps

5.00 g potassium-bromomethyl-trifluoroborate are added to a solution of 4.87 g tert-butyl piperazine-1-carboxylate in 25 ml of tetrahydrofuran. The mixture is stirred for 3 h at 80° C. and then cooled to ambient temperature. The solvent is removed, and the residue is suspended in 50 ml acetone and combined with 3.44 g potassium carbonate. The mixture is stirred overnight at ambient temperature. Then the mixture is filtered and the filtrate is evaporated down. The oil remaining is combined with diisopropylether and the colourless precipitate formed after a while is separated off and dried.
