実験手順
A solution of 1.00 g (2.5 mmol) of (S)-[5-phenyl-6-(triethylsilanyl)-7-H-pyrrolo[2,3-d]pyrimidine-4-yl]-(tetrahydrofuran-2-ylmethyl)-amine and 830 mg (3.7 mmol) of N-iodosuccinimide in 10 ml DMF was stirred at 45° C. for 1 h. The reaction mixture was partitioned between dichloromethane (120 ml) and a 4:1 mixture of brine and saturated aqueous sodium thiosulfate (35 ml). The organic layer was washed with saturated aqueous sodium bicarbonate (1×) and brine (1×), dried over Na2SO4, filtered and concentrated. The residue was dissolved in dichloromethane (10 ml), and hexanes (200 ml) was added slowly. A solid precipitate formed. The solid was filtered off and dried under high vacuum to give the title compound. 1H-NMR (400 MHz, CDCl3) δ 1.51 (m, 1 H), 1.69-1.91 (m, 3 H), 3.19-3.69 (m, 4 H), 3.99 (m, 1 H), 5.27 (t, J=4.4 Hz, 1 H), 7.37-7.56 (m, 5 H), 8.42 (s, 1 H), 13.21 (s, 1 H).
