Yield:31683-47-3 95%

Reaction Conditions:

with N-Bromosuccinimide in acetic acid at 20; for 2 h;

Steps:

1-Bromo-2-(trimethylsilyl)benzene (5)

A solution of 2a (1.112 g, 5 mmol) and NBS (1.068 g, 6 mmol) in AcOH(50 mL) was stirred at rt for 2 h followed by the workup procedure used for 4; the product was obtained as a colorless oil; yield: 1.083 g(95%).1H NMR (400 MHz, CDCl3): δ = 0.30 (s, 9 H), 7.07-7.11 (m, 1 H, ArH),7.15-7.19 (m, 1 H, ArH), 7.32-7.34 (m, 1 H, ArH), 7.43 (d, J = 8.0 Hz, 1H, ArH).13C NMR (100 MHz, CDCl3): δ = -0.58, 126.36, 130.56, 130.68, 132.71,136.04, 141.08.
