Reaction Steps

To 6-methoxy-7-(3-morpholinopropoxy)-4-((1-tertbutoxycarbonyl-1,2,3,4-tetrahydroquinolin-6-yl)oxy)quinazoline (110 mg, 0.2 mmol) in solution in dichloromethane (3 ml) was added TFA (0.3 ml) and the mixture stirred for 1 hour at ambient temperature. The solvents were evaporated and the remaining oil was diluted with dichloromethane and the pH adjusted to 9 with a saturated solution of sodium hydrogen carbonate. The organic phase was washed with, brine, dried (MgSO4), filtered and the solvent evaporated to give 6-methoxy-7-(3-morpholinopropoxy)-4-(1,2,3,4-tetrahydroquinolin-6-yloxy)quinazoline (84 mg, 93%).
