Sodium hydrosulfite (277.4 mg, 1.275 mmol) dissolved in water (1.5 mL) was added to a stirred solution of tert-butyl(1-(4-(methylamino)-3-nitrobenzoyl)piperidin-3-yl)carbamate (143.2 mg, 0.378 mmol) and 1-ethyl-1H-pyrrolo[3,2-c]pyridine-2-carbaldehyde (67.6 mg, 0.388 mmol) in ethanol (3.5 mL) at room temperature in a 5 ml microwave vial. The reaction mixture was then heated in a microwave for 5 hr at 100° C. Methanol was added to the reaction mixture and dried using Na2SO4. The reaction mixture was then filtered under gravity through a hydrophobic frit and the eluent collected and concentrated under vacuum. The crude product was dissolved in a minimum volume of DCM and purified using SP4 on a 25 g SNAP silica cartridge. The cartridge was eluted using a gradient of 0-100% 20% methanol in DCM/DCM. Appropriate fractions were collected and concentrated under vacuum to give the title compound as a yellow oil (76 mg).
