General method for preparation of intermediates 9e11 and54-68 General procedure: 15.0 mmol (1 eq) of aniline (or a series of amines), and potassiumcarbonate (30 mmol, 2 eq) was dissolved in 60 mL acetone,and stirred in an ice bath to 0° C. 2-chloropropionyl chloride (2-bromobutyryl bromide or 2-bromoisobutyryl bromide 18.0 mmol,1.2 eq)was slowly added dropwise and stirred at room temperaturefor 4 h. The reaction mixture was quenched with water andextracted with ethyl acetate. The organic layer was washed withwater and brine successively, dried over anhydrous sodium sulfate,and concentrated in vacuum. The resulting residue was purified bysilica gel chromatography (petroleum ether/EtOAc 10/1) to givethe desired intermediates 9-11 and 54-68.

The solution was filtered. Theexcess of solvent was removed under suction and cold water wasadded to get a clear solution. The solution was again filtered toremove suspended particles. Then N-substituted-chloroalkylamide(1 mol) was added in small portion at room temperature withstirring, then stirring was continue between 60 and 65 C for 8 hcooled and extracted with EtOAc. The EtOAc layer was dried withsodium sulphate and the column purified.
