    Abstract: Preparation of bicyclic amidine derivatives with continual removal of water during reaction. Bicyclic amidine derivatives of formula (1) are prepared by reacting a lactone of formula (2) with a diamine of formula (3), during which water is removed while the reaction is taking place. Rx, Ry, Ra, Rb = independently H, or 1-10C alkyl, 2-10C alkenyl, 2-10C alkynyl or 6-12C aryl, optionally substituted by OH, NH2, 1-4C alkylamino or SH; m, n = 2-12; a, b, x and y actually = number of carbon atoms in the R groups, which correspond to values of n+1 or m+1. Independent claims are also included for the following: (I) A diazacycloalkane of formula (4); (II) Preparation of diazacycloalkane (4); and (III) Use of diazacycloalkane (4) as an intermediate in production of bicyclic amines of formula (1). Rx, Ry, Ra, Rb = independently H, or 1-10C alkyl, 2-10C alkenyl, 2-10C alkynyl or 6-12C aryl, optionally substituted by OH, NH2, 1-4C alkylamino or SH; m, n = 2-12; a, b, x and y actually = number of carbon atoms in the R groups, which correspond to values of n+1 or m+1.
