Abstract

C 16 H15NO5, monoclinic, P21/n (no. 14), a = 6.7689(5) Å, b = 45.219(3) Å, c = 10.1102(6) Å, β = 101.360(7)°, V = 3033.9(4) Å 3 , T = 298(2) K. CCDC no.:1525292 Tables 1 and 2 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. Source of materialA solution of oxalyl chloride (1 mole equivalent) in dichloromethane (DCM) was added dropwise to a solution of bis(4-methoxyphenyl)amine (1 mole equivalent) in DCM in the presence of triethylamine at room temperature. The mixture was stirred for 1.5 h and water was added. The organic layer was separated, dried over anhydrous
