Reaction Steps

To a solution of 3-(pyridin-3-yl)-7-[1-(2-aminoethyl)-6-(4-fluorophenyl)indol-3-ylcarbonyl]-1H,3H-pyrrolo[1,2-c]thiazole (0.20 g, 0.062 mmol), prepared according to the method of Example 59, and triethylamine (13 μL, 0.093 mmol) in THF (15 mL) was added methanesulfonyl chloride (6 μL, 0.074 mmol). The reaction mixture was stirred for two hours at ambient temperature. The reaction mixture was quenched with saturated aqueous NH4Cl and extracted with ethyl acetate. The organic phase was washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. 3-(Pyridin-3-yl)-7-[1-(2-methanesulfonylaminoethyl)-6-(4-fluorophenyl)indol-3-ylcarbonyl]-1H,3H-pyrrolo[1,2-c]thiazole (66 mg) was obtained by flash chromatography on silica gel (98:2 CHCl3, methanol), 1H NMR (CDCl3, 300 MHz) δ2.83 (s, 3H), 3.6 (d, 2H, J=6 Hz), 4.42-4.52 (m, 3H), 4.65 (d, 1H, J=15 Hz), 5.57 (bs, 1H), 6.38 (bs, 1H), 6.46 (bs, 1H), 6.8 (d, 1H, J=3 Hz), 7.15 (t, 2H, J=9 Hz, 11 Hz), 7.47 (d, 2H, J=7 Hz), 7.52 7.65 (m, 3H), 7.8 (d, 1H, J=9 Hz), 7.95 (s, 1H), 8.38 (d, 1H, 9 Hz), 8.55 (bs, 2H). MS (DCI/NH3) m/e 561 (M+H)+. Anal calcd for C29H25FN4O3S2 : C, 62.13; H, 4.49; N, 9.99. Found: C, 61.37; H, 4.57; N, 9.58.
