Procedure

A procedure similar to that described in Example 6, was repeated, except that 5.40 g of 2-methylamino-3-nitro-6-phenylthiopyridine (prepared as described in Preparation 88) were hydrogenated in 80 ml of methanol in the presence of 1.10 g of 10 % w/w palladium-on-charcoal. After working up the product as described in Example 6, 4.00 g of the title compound having Rf=0.69 (on silica gel thin layer chromatography using ethyl acetate as the developing solvent) were obtained.
