Participants

Reaction Steps

To a solution of (±)-(7-methyl-4-(((tetrahydro-2H-pyran-2-yl)oxy)methyl)-1-tosyl-1H-indol-5-yl)methanol (Example 52-C) (170 mg, 0.40 mmol) in DMF (1 mL) was added NaH (31.7 mg, 60% in mineral oil, 0.79 mmol) at room temperature, and then the mixture was stirred for 10 min. To the mixture was added MeI (25 uL, 0.40 mmol) at room temperature, and then the mixture was stirred for 2.5 h. The reaction was quenched by half saturated aqueous solution of KHSO4, and diluted with EtOAc. The bi-layer was partitioned. The organic phase was washed successively H2O and brine, dried over Na2SO4, and then filtered. Concentration of the filtrate gave the title compound, without need of any further purification. 1H NMR (400 MHz, DMSO-d6) δ 7.86 (d, J=3.79 Hz, 1H), 7.62 (d, J=8.34 Hz, 2H), 7.39 (d, J=8.34 Hz, 2H), 7.08 (s, 1H), 6.99 (d, J=3.79 Hz, 1H), 4.87 (d, J=11.37 Hz, 1H), 4.67 (d, J=11.37 Hz, 1H), 4.60-4.64 (m, 1H), 4.44-4.54 (m, 2H), 3.73-3.86 (m, 1H), 3.41-3.52 (m, 1H), 3.30 (s, 3H), 2.47 (s, 3H), 2.34 (s, 3H), 1.51-1.78 (m, 2H), 1.34-1.51 (m, 4H).
