PROCEDURE

实验过程

2'-Methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)biphenyl-4-carboxylic acid (EP 0553268A1) (0.188 g, 0.64 mmol) was converted to the acyl chloride by stirring at reflux under Ar in thionyl chloride (10 ml) for 45 min, cooling, and then evaporating to dryness. This was reacted with 6-amino-4(2-dimethylaminoethyl)-1,4-benzoxazin-3(4H)-one (D8) (0.150 g, 0.64 mmol) following the procedure of Example 1. This gave the title compound (0.247 g, 75%) as a white foam, which was converted to the oxalate, a white solid.
