Participants

Reaction Steps

Using an analogous procedure to that described in the last paragraph of the portion of Example 1 which is concerned with the preparation of starting materials, a mixture of 3-(4-benzyloxybenzamido)-N-(3-dimethylaminophenyl)-4-methylbenzamide (0.227 g), 10% palladium-on-carbon (0.028 g), ammonium formate (0.37 g) and methanol (20 ml) was stirred and heated to reflux for 1.5 hours. The mixture was cooled to ambient temperature and filtered through diatomaceous earth. The filtrate was evaporated and the residue was triturated under water. The resultant solid was washed with a 100:1:0.12 mixture of methylene chloride, methanol and a saturated aqueous ammonium hydroxide solution and dried under vacuum at 55° C. There was thus obtained the title compound as a solid (0.104 g); NMR Spectrum: (DMSOd6) 2.26 (s, 3H), 2.84 (s, 6H), 6.44 (d, 1H), 6.84 (d, 2H), 7.13 (m, 3H), 7.39 (d, 1H), 7.76 (d, 1H), 7.86 (d, 2H), 7.92 (s, 1H), 9.73 (s, 1H), 9.91 (s, 1H); Mass Spectrum: M+H+ 391.
