7-Benzyloxy-4-chloro-3-nitroquinoline (66.4 g, 0.21 mol) was dissolved in a mixture of dichloromethane (1.5 L) and triethylamine (59 mL, 0.422 mol). A solution of 1-amino-2-methyl-2-propanol (22.5 g, 0.25 mol) in dichloromethane (100 mL) was added dropwise. The reaction was stirred at ambient temperature for 3 hours and then quenched with 1% aqueous sodium carbonate solution. A precipitate formed which was filtered to provide 60 g of crude 1-(7-benzyloxy-3-nitroquinolin-4-ylamino)-2-methylpropan-2-ol as a yellow-brown solid.
