実験手順
A stirred solution of the Step 1 intermediate (20 g, 120.463 mmol) in acetonitrile (200 ml) was reacted with ceric ammonium nitrate (33 g, 60.233 mmol) followed by iodine (18 g, 72.281 mmol) according to the procedure described in Intermediate 1, Step 3 to give 35 g of the product as a light yellow solid; 1H NMR (300 MHz, DMSO-d6) δ 2.56 (s, 3H), 7.52 (d, J=5.1 Hz, 1H), 7.97 (d, J=4.8 Hz, 1H); ESI-MS (m/z) 291.29 (M−H)−.
