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.
The present invention relates to novel compounds of formula (I), process for preparation of the same and composition comprising these compounds.

A facile synthesis of imidazoles and tetrazoles via [3+1+1] type cyclization of ClCF2COONa is developed. A diverse array of imidazoles and tetrazoles were obtained in decent yields via isocyanide intermediates. Notably, this is the first example of the cycloaddition of in situ generated isocyanides.
The present invention relates to novel compounds of formula (I) as GPR119 agonist, composition compositions containing such compounds and method of preparation thereof.
