Participants

Reaction Steps

A solution of 3.38 g (10.9 mmoles) of trans-6-chloro-4-(2-fluorophenyl)-1,3-benzodioxan-2-carboxylic acid, 10.0 ml (16.4 g, 137 mmoles) of thionyl chloride, and 5 drops of anhydrous DMF in 200 ml of anhydrous Ch2Cl2 was refluxed for 2 hours; the solvent and excess SOCl2 were removed under reduced pressure and the residue was flashed down with 3 portions of anhydrous benzene to remove traces of SOCl2. The acid chloride was redissolved in 100 ml of anhydrous CH2Cl2 and 5.57 ml (3.86 g, 65.4 mmoles) of 2-aminopropane was added all at once; heat was evolved. The reaction mixture stood in a stoppered flask for 16 hours.
