Reaction Steps

N-((3S,4S)-4-azidotetrahydro-2H-pyran-3-yl)-6-(2,6-dichloro-3,5-dimethoxyphenyl)quinazolin-2-amine (0.063 g, 0.133 mmol) was taken up in Methanol (7 ml) and EtOAc (7.00 ml), Pd—C (0.014 g, 0.133 mmol) was added and stirred under a H2 balloon for 1 hour. After the reaction was completed, it was filtered through celite and the solvent removed. (3S,4S)—N3-(6-(2,6-dichloro-3,5-dimethoxyphenyl)quinazolin-2-yl)tetrahydro-2H-pyran-3,4-diamine (0.060 g, 0.134 mmol, 101% yield) was recovered as a yellow solid, which was carried on without further purification. MS (ES+) C21H22Cl2N4O3 requires: 448, found: 449 [M+H]+.
