Thus, in the reaction of Equation 43a, 2-nitrobenzoyl chloride LVII is reacted with potassium thiocyanate in a solvent such as toluene or acetonitrile at reflux for 0.2 to 5 hours; the resultant benzoyl thiocyanate is then reacted with excess methanol, ethanol or methyl mercaptan at 25° to 80° C. for 0.2 to 5 hours to form an O-alkyl benzoylthiocarbamate or methyl benzoyldithiocarbamate of Formula (LVIII). In reaction 43b, LVIII is reacted with sodium methoxide and methyl iodide in methanol at 0° to 25° C. for 1 to 5 hours to form a dialkyl benzoyliminothiocarbonate or dimethyl benzoyliminodithiocarbonate of Formula (LIX). And in reaction 43c, LIX is reacted with hydroxylamine in methanol or ethanol at 0° to 25° C. for about 10 to 96 hours to form Xm'.
