Experimental Section

General: IR spectra were recorded on a Bruker Tensor 37 (FTIR) spectrophotometer. 1H NMR spectra

were recorded on Bruker Avance 400 (400 MHz) spectrometer at 295 K in CDCl3; chemical shifts (δ in

ppm) and coupling constants (J in Hz) are reported in standard fashion with reference to either internal

standard tetramethylsilane (TMS) (δH = 0.00 ppm) or CHCl3 (δH = 7.25 ppm). 13

C NMR spectra were

recorded on Bruker Avance 400 (100 MHz) spectrometer at RT in CDCl3; chemical shifts (δ in ppm) are

reported relative to CHCl3 (δC = 77.00 ppm). In the 1H-NMR, the following abbreviations are used

throughout: s = singlet, d = doublet, t = triplet, q = quartet, qui = quintet, m = multiplet and br s = broad

singlet, sept = septet. The assignment of signals were confirmed by 1H and

13C spectral data. High-

resolution mass spectra (HR-MS) were recorded on an Agilent 6538 UHD Q-TOF using multimode

source. Microwave experiments were carried out with CEM Discover LabmateTM

instrument in 10 ml

vial, closed vessel, Power: 250W, Temperature: 60 °C-100 oC for 50-100 minutes. Melting points were

determined using melting point apparatus manufactured by GUNA enterprises, India and are uncorrected.

All small scale reactions were carried out using standard syringe-septum technique. Reactions were

monitored by TLC on silica gel using a combination of hexane and ethyl acetate as eluents. Solvents were

distilled prior to use.

General Procedure for the synthesis of 2-amino-substituted-4(3H)-quinazolinones (5a-5v):

In an oven dried schlenk tube under argon atmosphere, were added isatoic anhydride (1 equiv, 0.609

mmol), amine (1 equiv, 0.609 mmol) and activated 4Å molecular sieves (150 mg) followed by addition of

dry DMSO (2 mL). The reaction mixture was stirred at 110 oC for 30 min to 4 h. The completion of first

step was monitored by TLC. Once dinucleophile was formed Pd(OAc)2 (5 mol%), CyNC (1.5 equiv.,

0.913 mmol) were added in same pot under argon atmosphere. It was evacuated and filled with O2 by

using a balloon. The resulting reaction mixture was heated at 110 oC. Progress of the reaction was

monitored by TLC, which took 15-17 h. The reaction mixture was then quenched with water and the

product was extracted with ethyl acetate. The organic layer was dried over Na2SO4 and concentrated in

vacuo. The crude product was purified by column chromatography on silica gel using petroleum

ether/ethyl acetate as eluent, which afforded the desired product (5a-5w). All the compounds were

confirmed by FTIR, 1H NMR,

13C NMR and HR-MS Spectral analyses. Among 22 compounds,

19 are unknown and 3 (5a, 5i & 5m) are known.
