Diisopropylethylamine → HCID 86701546、化合物

To a solution (±)-(7-methyl-4-(((tetrahydro-2H-pyran-2-yl)oxy)methyl)-1-tosyl-1H-indol-5-yl)methanol (200 mg, 0.466 mmol) and iPr2EtN (0.16 mL, 0.93 mmol) in CH2Cl2 (2 mL) was added SEMCl (0.124 mL, 0.69 mmol), and then the mixture was stirred at 40° C. for 1 hr. The reaction mixture was concentrated (during the concentration, the THP group was partially removed) and then purified by SiO2 column chromatography (heptane/EtOAc=1/0 to 1/3) to give the title compound. 1H NMR (400 MHz, ACETONITRILE-d3) δ 7.81 (d, J=3.79 Hz, 1H), 7.58 (d, J=8.30 Hz, 2H), 7.32 (d, J=8.30 Hz, 2H), 7.08 (s, 1H), 6.99 (d, J=3.79 Hz, 1H), 4.79 (d, J=5.81 Hz, 2H), 4.68 (s, 2H), 4.67 (s, 2H), 3.54-3.63 (m, 2H), 3.05 (t, J=5.80 Hz, 1H), 2.54 (s, 3H), 2.35 (s, 3H), 0.82-0.96 (m, 2H), 0.01 (s, 9H).
