Reaction Conditions

Reaction Steps

A solution of 350 mg of lithium hydroxide monohydrate dissolved in 10 ml of water was added to a solution of 0.70 g of ethyl 2-{N-[(2'-methoxalylbiphenyl-4-yl)methyl]-N-propylamino}nicotinate [prepared as described in step (a) above] dissolved in 5 ml of dioxane, and the resulting mixture was stirred at 70° C. for 4 hours. At the end of this time, the dioxane was removed by distillation under reduced pressure, and 8.33 ml of 1N aqueous hydrochloric acid were added to the residual aqueous solution. The crystals thus precipitated were collected by filtration, to give 0.57 g of the title compound, melting at 179°-180° C.
