Participants

Reaction Steps

2-Bromo-5-chloro-1H-pyrrolo[3,2-b]pyridine (2.0 g, 8.6 mmol, prepared as in Example 103, Step 1) in DMF (20. mL) was treated with K2CO3 (1.8 g, 13 mmol) and m-cyanobenzyl bromide (1.9 g, 9.5 mmol, Aldrich) overnight. The reaction mixture was diluted with EtOAc and washed sequentially with water and brine. The combined organic extracts were dried over sodium sulfate, filtered and concentrated. The solid obtained was triturated with hexanes/diethyl ether and isolated by filtration. Yield: (2.3 g, 77%).
