Yield: 8.04 g

Reaction Conditions:

with dmap;triethylamine in dichloromethane at 20; for 1 h;

Steps:

23 Synthesis of (5-bromo-2-pyridyl)-(1-methylindol-3-yl)methanone (Intermediate 33)
Method 23
Synthesis of (5-bromo-2-pyridyl)-(1-methylindol-3-yl)methanone (Intermediate 33)
To a solution of R-8 (5.00 g, 34.45 mmol), DMAP (0.42 g, 3.44 mmol) and triethylamine (9.6 mL, 68.89 mmol) in DCM (300 mL) is added di-tert-butyl dicarbonate (8.27 g, 37.89 mmol) and the resultant solution stirred at room temperature for 1 h.
The solution is washed with saturated aqueous NH4Cl and brine then dried over anhydrous Na2SO4.
The solvent is removed in vacuo to give I-29 (8.04 g).
