• Rb, Rc and Rd are independently hydrogen, alkyl or substituted alkyl, cycloalkyl or substituted cycloalkyl, heterocycle or substituted heterocycle, or aryl or substituted aryl, or said Rb and Rc together with the N to which they are bonded optionally form a heterocycle or substituted heterocycle;
• and
• Re is alkyl or substituted alkyl, alkenyl or substituted alkenyl, alkynyl or substituted alkynyl, cycloalkyl or substituted cycloalkyl, cycloalkenyl or substituted cycloalkenyl, heterocycle or substituted heterocycle, or aryl or substituted aryl, comprising reacting a compound of formula VII,
• wherein R1, R4, R7, and R8 are defined as hereinabove, and X is a leaving group selected from Cl Br, I, and —OSO2R, in which R is alkyl, substituted alkyl, aryl or substituted aryl, with a compound of formula VIII,
• wherein R5 is defined as hereinabove, to provide the compound of formula VI.
