PROCEDURE

实验过程

A mixture of (S)-2-ethyl-4-(2-propyl)-3-oxo-3,4-dihydro-2H-1,4-benzoxazine-7-carboxylic acid (0.70 g) in thionyl chloride (15 ml) was stirred under reflux for 2 hours. Thionyl chloride was distilled off under reduced pressure to give (S)-2-ethyl-4-(2-propyl)-3-oxo-3,4-dihydro-2H-1,4-benzoxazine-7-carbonyl chloride (0.70 g).
