Abstract

The reductive amination of carboxylic acids was shown to be promoted by 2-chloropyridine hydrochloride (3 eq). It allowed the one-pot preparation of N-alkylamines in yields up to 93% from carboxylic acid (1 eq), amine (1 eq) and sodium borohydride (5 molar eq). The reaction, carried out with [11C] magnesium halide carboxylates (11C, β+, t1/2∶ 20 min), led to N- [11C] alkylamines in 20–25% radiochemical yields (decay corrected to the end of ...
