Procedure

A mixture of sodium triacetoxyborohydride (104 mg, 0.493 mmol) and (2R,3R)-2-amino-N-cyclopentyl-3-methylpentanamide (48.9 mg, 0.246 mmol) in DCE (2 mL) was stirred at room temperature for 30 min. To this mixture was added 1-tert-butyl 3-methyl 4-formyl-1H-pyrrolo[2,3-b]pyridine-1,3-dicarboxylate (75 mg, 0.246 mmol). The reaction mixture was stirred at room temperature for 1 h and was subsequently concentrated to afford the title compound as a crude intermediate. [M+H] calc'd for C26H38N4O5, 487; found, 487.7.
