Procedure

Ethyl 7-(7-formyl-2,3-di-p-tolyl-5H-pyrrolo[2,3-b]pyrazin-5-yl)heptanoate (Intermediate C)(50 mg, 0.103 mmol) in DCE (1 ml) was treated with iso-propylamine (0.027 ml, 0.310 mmol) and stirred at RT for 30 minutes. Sodium triacetoxyborohydride (65.7 mg, 0.310 mmol) was added and stirring continued at RT for 16 hours. The mixture was extracted with DCM (30 ml) and the organic extract was washed with water (×2) and concentrated under reduced pressure to afford the titled compound as an orange oil;
