Reaction Steps

To a solution of methyl 2-[(trans-4-hydroxycyclohexyl)amino]quinazoline-7-carboxylate (3090 mg, 10.3 mmol) in THF (100 mL) was added MeOH (20 mL) followed by 2 M NaOH (20 mL, 40 mmol) and the mix stirred at R.T. for 3 hours. The solvents were stripped and the mix acidified with a stoichiometric amount of 1M HCl giving a yellow precipitate that was filtered off and washed with water and air dried to yield the title compound as a bright yellow solid, 2.7 g, 92%. 1H NMR (400 MHz, DMSO-D6) δ ppm 13.30 (1H, s) 9.17 (1H, s) 7.96 (1H, s) 7.85 (1H, d, J=8.34 Hz) 7.64 (1H, d, J=8.34 Hz) 7.48 (1H, s) 4.57 (1H, s) 3.79 (1H, s) 1.79-2.04 (4H, m) 1.17-1.43 (4H, m); MS (API−) for C15H17N3O3 m/z 286.1 (M−H)+.
