Reaction Steps

In analogy with Example 2, reacting guanidine with methyl 3-methylsulfonyl-4-(6-methyl-3-pyridyloxy)benzoate [obtainable by reacting 3-methylsulfonyl-4-chlorobenzoic acid with 6-methyl-3-trimethylsilyloxypyridine and subsequently esterifying the product with methyl iodide/K2CO3 in DMF] gives N-diaminomethylene-3-methylsulfonyl-4-(6-methyl-3-pyridyloxy)benzamide, m.p. 197-199°.
