In a recent paper (New J. Chem., 2001, 25, 1520), we have analysed crystal structures of some N-aryl pyrimidinones. Based on the occurrence of two-dimensionallayers in six out of nine crystals, we proposed that self-assembly in these structures might be analysed in terms of the stacking of 2D hydrogen-bonded layers. We show herein that meta-substituted phenyl pyrimidinones (Br, I, F, NO2, Me, OMe)

The present invention provides a novel heterocyclic compound. A heterocyclic compound represented by general formula (1) wherein, R
1
and R
2
, 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; R
3
represents a lower alkynyl group or the like; R
4
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.
