The alcohol from Step 1, 6-(3-nitro-quinolin-4-ylamino)hexan-1-ol (10.0 g, 34.6 mmol), was oxidized by the general method described in Step 6 of Example 1 with DMSO (4.05 g, 51.8 mmol), oxalyl chloride (4.83 g, 38.0 mmol), and triethylamine (10.5 g, 104 mmol) to provide 6-(3-nitroquinolin-4-ylamino)hexanal (9.9 g) as a bright yellow solid that was used directly in the next step without further purification.
