Abstract
The key intermediate 5 of a large number of potent AT(1) selective ang iotensin II antagonists e.g. the potent cyclopropylmethyl derivative 1 (EMD 69943) was synthesized by regioselective alkylation of carbamate 3 with the well-known 4'-(bromomethyl)biphenyl-2-carbonitrile (4) and n-butyllithium as the preferred base.
