Procedure

12 g (45.8 mmol) of triphenylphosphine are added in a single portion to a solution of 8.7 g (37.8 mmol) of 4-azido-5,8-dimethoxyquinoline in a THF/H2O mixture (110 mL/110 mL). The reaction medium is stirred at ambient temperature for 2 hours and then concentrated on a rotary evaporator. The residue is acidified with 200 mL of 1N HCl and extracted with ether (3 times 500 mL). The aqueous phase is then basified with 250 mL of 1N NaOH and re-extracted with CHCl3 (3 times 250 mL). After drying over MgSO4 and evaporating off the solvent on a rotary evaporator, the expected amine is obtained quantitatively in the form of brown powder, which decomposes before melting.
