Participants

Reaction Steps

To 2M NH3 in methanol (0.6 mol), cooled in an ice bath under Ar, was added intermediate (16) (0.0574 mol) dissolved in methanol (150 ml). The mixture was allowed to warm to room temperature and stir under argon for 6 hours. The reaction was concentrated to 150 ml and filtered. The solid was rinsed with a small amount of cold methanol and allowed to dry, yielding 2.33 g of 5-fluoro-2,3-dihydro-1H-indole-2-carboxamide (intermediate 17, mp. 197-199° C.).
