Sodium triacetoxyborohydride → n-Cyclopropyl-2,4-difluoro-5-((2-phenyl-1h-pyrrolo[2,3-b]pyridin-5-yl)methylamino)benzamide

Participants

Reaction Steps

To a solution of compound D of Example 1 (22 mg, 0.1 mmol), in a mixture of acetic acid and dichloromethane (1:1, 1 mL) were added 5-amino-N-cyclopropyl-2,4-difluorobenzamide (30 mg, 0.15 mmol) and NaBH(OAc)3 (30 mg, 0.2 mmol). The mixture was stirred at RT for 1 h. The reaction mixture was concentrated and the residue was purified by preparative RP HPLC. The appropriate fractions were collected and concentrated to remove methanol and saturated solution of NaHCO3 was added to precipitate out the desired product. The solid was filtered and dried in vacuo to give the title compound (6.5 mg) as a solid. LC/MS; (M+H)+=419.2
