실험 절차

The product from Example 136A (5.76 g, 27 mmol) was suspended in concentrated aqueous ammonia (400 mL) and treated with a solution of potassium iodide (23.3 g, 140 mmol) and iodine (7.24 g, 28.5 mmol) in water (100 mL). As the reaction did not go to completion, the mixture was treated with a second solution of potassium iodide (15.8 g, 95 mmol) and iodine (4.83 g, 19 mmol) in water (50 mL). After an hour the ammonia was removed under reduced pressure on a rotary evaporator. The mixture was extracted with EtOAc, and the combined organic phases were washed consecutively with pH 6 potassium phosphate buffer and brine, then dried (Na2SO4), concentrated, and chromatographed through silica with 1% acetic acid in a gradient of 0 to 5% EtOAc/CH2Cl2 to provide the title compound as a beige powder (21% yield). MS (ESI APCI negative ion detection) m/z 337 (M−H)−; 1HNMR (300 MHz, CDCl3) δ 2.65 (s, 3 H), 5.37 (bs, 1 H), 7.08 (d, 1 H), 7.48-7.55 (m, 2 H), 7.71 (ddd, 1 H), 7.88-7.93 (m, 2 H), 8.09 (dd, 1 H).
