    摘要: An efficient process for the preparation of styrylbenzoxazoles and derivatives thereof comprises reacting a methylbenzoxazole with an aromatic aldehyde in the presence of strong base at low temperature, followed by warming. The condensation products are inhibitors of H.sup.+ K.sup.+ -ATPase, and are also useful as penultimate compounds in the preparation of inhibitors of HIV reverse transcriptase.

    摘要: The present invention is directed to a novel process for the preparation of the compound N-�1(R)-�(1,2-dihydro-1-methanesulfonyl-spiro�3H-indole-3,4'-piperdin!-1'-yl)carbonyl!-2-(phenylmethyl-oxy)ethyl!-2-amino-2-methyl-propanamide, and salts thereof, which has the structure: ##STR1## and which has the ability to stimulate the release of natural or endogenous growth hormone. This compound may be used to treat conditions which require the stimulation of growth hormone production or secretion such as in humans with a deficiency of natural growth hormone or in animals used for food or wool production where the stimulation of growth hormone will result in a larger, more productive animal.
