2-Propanethiol → 5-Nitro-2-(propane-2-sulfonyl)benzonitrile

Participants

Reaction Steps

Using a procedure analogous to that used to prepare 6A, 2-fluoro-5-nitrobenzonitrile (2.50 g, 15.6 mmol) was reacted with isopropylthiol and oxidized with mCPBA to afford 9A (3.04 g, 91%) as a white solid. 1H NMR (400 MHz, CDCl3) δ 1.40 (d, J=7.03 Hz, 6 H), 3.55-3.76 (m, 1 H), 8.38 (d, J=8.35 Hz, 1 H), 8.63 (dd, J=8.79, 2.20 Hz, 1 H), 8.74 (d, J=2.64 Hz, 1 H).
