Procedure

A procedure similar to that described in Example 6 was repeated, except that 5.00 g of 2-methylamino-3-nitropyridine (prepared as described in Preparation 104) were hydrogenated in 80 ml of 1,4-dioxane in the presence of 1.00 g of 10% w/w palladium-on-charcoal. After working up the product as described in Example 6, 3.87 g of the title compound, melting at 90-92° C. were obtained.
