Title compds. (I; R1 and R2 and H; R3 = H, lower alkyl or alkoxyalkyl; X = S; Y= =S, =O, =NR5 or =CHR6; Alk = C1-6 alkylene; R5 = H, nitro, cyano, lower alkyl, aryl, alkylsulfonyl or arylsulfony; R6 = arylsulfonyl or alkylsulfonyl; n = 1;m = 2-4) were prepd. by the reaction of compd. IV and II(R1 and R2 are H; R7 = H) or III. Thus, 0.5 g 5-[5-dimethylamino)methyl-2-furanyl pentaneamine and 0.25 g methylisothiocyanate were stirred for 24 hr in acetonitrile to give N-[5-[5-(dimethylamino)methyl-2-furanyl pentyl -N'-methylthiourea.
