The present invention provides a novel heterocyclic compound. A heterocyclic compound represented by general formula (1) wherein, R1 and R2, each independently represent hydrogen; a phenyl lower alkyl group that may have a substituent(s) selected from the group consisting of a lower alkyl group and the like on a benzene ring and/or a lower alkyl group; or a cyclo C3-C8 alkyl lower alkyl group; or the like; R3 represents a lower alkynyl group or the like; R4 represents a phenyl group that may have a substituent(s) selected from the group consisting of a 1,3,4-oxadiazolyl group that may have e.g., halogen or a heterocyclic group selected from pyridyl group and the like; the heterocyclic group may have at least one substituent(s) selected from a lower alkoxy group and the like or a salt thereof.

A new class of potent antihypertensives has been discovered that exert their effect through blockade of the angiotensin II (AII) receptor. Most AII antagonists reported so far are peptide mimics of the endogenous vasoconstrictor octapeptide angiotensin II. The compounds of this paper are nonpeptides and therefore constitute a new class of potent AII receptorantagonists. Based on the overlap of a conformation

There is provided herein a process for the preparation of aluminum salts of phosphonic acid esters by reacting phosphonic acid diesters with aluminum hydroxide in the presence of a catalyst. The catalyst is selected from the group consisting of a phase transfer catalyst, a thermally stable tertiary amine having a boiling point higher than about 140°C, a thermally stable tertiary phosphine having a boiling point higher than 140°C and combinations thereof. The aluminum phosphonates prepared can be used for making flame retarded thermoplastic polymers.

x is an integer from 1 to 20,
to form hydrogen halide in the presence of an auxiliary base, in which the auxiliary base forms, with the hydrogen halide, a salt which forms two immiscible phases with the siloxy carboxylate or the solution of the siloxy carboxylate in a suitable solvent and is removed by a liquid-liquid separation. The process enables simple and economically viable preparation of siloxy carboxylates.
