Reaction Conditions

Reaction Steps

A partial suspension of 1 2-diethoxalylaminonaphthalene (1,79 g, 5 mmol) in 7 ml of acetic acid and 7 ml of acetic anhydride was treated dropwise with a solution of nitric acid (1.8 ml, 43 mmol, d 1.52) in 7 ml of acetic acid, with stirring at 0° C. The resulting solution was stirred at 0° C. for 11/2 h and then poured on 150 ml of ice/water. The yellow precipitate was isolated, dried and recrystallized from ethanol with decolourising carbon giving 0.67 g (33%) of the required compound, m.p. 173-175° C.,1H-NMR (CDCl3 +DMSO-d6), 1,43 (t,J=7 Hz, 6H,2 CH3), 4.40 (q,J=7Hz, 2H, CH2), 4.42 (q,J=7Hz, 2H, CH2), 7.3-8.4 (m, 5H, ArH).
