Sodium hydrosulfite (162 mg, 0.793 mmol) dissolved in water (1 mL) was added to a solution of (R)-tert-butyl(1-(4-(methylamino)-3-nitrobenzoyl)piperidin-3-yl)carbamate (100 mg, 0.264 mmol) and 1-ethyl-1H-pyrrolo[2,3-c]pyridine-2-carbaldehyde (46.0 mg, 0.264 mmol) in ethanol (2 mL) at RT under nitrogen. The reaction mixture was heated to 100° C. in a microwave for 5 h. The reaction mixture was diluted with DCM (20 mL), sodium sulfate was added and the resultant suspension filtered and concentrated in vacuo to yield the crude product. This was purified by Biotage SP4 on a SNAP 10 g silica cartridge using a gradient of 0% (20% MeOH/DCM)/DCM→50% (20% MeOH/DCM)/DCM. Appropriate fractions were combined and evaporated under vacuum to give the title compound (42 mg)
