- METHOD OF PREPARING A 5H-DIBENZ[B,F]AZEPINE-5-CARBOXAMIDE
-
The present invention provides a method of preparing a 5H-dibenz[b,f]azepine-5-carboxamide of formula (1) wherein R1, R2, R3, and R4 are independently selected from the group consisting of hydrogen, halogen, nitro, cyano, carboxyl, A, -CO(A), -OCO(A), -O(A), -N(A)2, -CON(A)2, and -COO(A), wherein A is selected from the group consisting of C-1-C10 alkyl, C3-C10 cycloalkyl, C-2-C10 alkenyl, C-5-C10 cycloalkenyl, C-2-C10 alkynyl, and C-6-C20 aryl, wherein the two A groups of -N(A)2 and -CON(A)2 can be the same or different, and wherein R2 and R3 can together form a bond; comprising reacting a 5H-dibenz[b,f]azepine of formula (2) with a) a cyanate salt selected from the group consisting of alkali metal cyanate salts and alkaline-earth metal cyanate salts, and b) a salt of an amino compound having no N-H bonds, wherein the salt has a Ka (25° C) of at least about 10 x 10-11.
