TBDMS-Cl (2.7 g, 18.24 mmol) was added at 0° C. to a stirred solution of aniline 11 (3 g, 15.62 mmol) and TEA (1.73 g, 17.18 mmoles) in DMF and the reaction mixture was stirred at RT for 4 h. The reaction mixture was partitioned between EtOAc and water. Organic layer was washed with water 2×, dried over sodium sulfate and concentrated under reduced pressure to give 3(tert-butyldimethylsilyloxy)-3-(3-nitrophenyl)propanenitrile as colorless liquid. Yield (4.0 g, 83%); 1H NMR (400 MHz, DMSO-d6) δ 8.31 (s, 1H), 8.18 (d, J=7.6 Hz, 1H), 7.88 (d, J=7.6 Hz, 1H), 7.70 (t, J=7.6 Hz, 1H), 5.33 (t, J=5.6 Hz, 1H), 3.01-2.92 (m, 2H), 0.88 (s, 9H), 0.13 (s, 3H), −0.05 (s, 3H).
