A synthesis of L-692429 has been reported: The cyclization of isobutene (I) with chlorosulfonyl isocyanate (II) gives 1-(chlorosulfonyl)-4,4-dimethylazetidin-2-one (III), which is condensed with 3(R)-amino-2,3,4,5-tetrahydro-1H-1-benzazepin-2-one (IV) by means of triethylamine in methanol to yield 3-methyl-3-(methylsulfonamido)-N-[2-oxo-2,3,4,5-tetrahydro-1H-1-benzaze pin-3(R)-yl]butyramide (V). The reaction of (V) with 2'-[1-(triphenylmethyl)tetrazol-5-yl]biphenyl-4-ylmethyl bromide (VI) by means of NaH in THF/DMF affords protected L-692429, which is finally deprotected by a treatment with 5N HCl.
