Experimental and theoretical studies of the title molecule were carried out to analyse its preferential conformation according to the usual energetic criteria and also examine its IR and Raman spectra. Molecular orbital calculations were performed via the semiempirical AM1 and PM3 methods and ab ini

## Abstract The 6‐(3‐hydroxypropylamino)‐3‐methylpyrimidine‐2,4‐dione (1) did not afford the expected 6‐(3‐chloro‐propylamino)‐ derivative on reaction with thionyl chloride, but, instead, the pyrimidine rings were joined __via__ a sulfur bridge to give 9,9′‐thiobis(1,2,3,4,7,8‐hexahydro‐7‐melnyl‐6_
