The benzylamine was obtained by reacting 5-(piperidin-4-ylmethoxy)quinazoline-2,4-diamine (75 mg; 0.27 mmol) and 2,4-difluorobenzyl chloride (69 mg; 0.35 mmol) via Method BB. Solids were suspended in 2 mL dioxane and 0.5 mL 4M HCl in dioxane was added and after 2 hours stirring at room temperature solids were collected by filtration to yield 92 mg. (78% yield). 1HNMR (400 MHz, DMSO-d6) δ 12.8 (s, 1H), 11.2 (s, 1H), 8.84 (s, 1H), 8.23 (s, 1H), 7.88 (q, J=8.8, 6.4 Hz, 1H), 7.7 (m, 2H), 7.4 (m, 1H), 7.23 (m, 1H), 7.02 (m, 2H), 4.28 (d, J=4.4 Hz, 2H), 4.17 (d, J=6.4 Hz, 2H), 3.4 (br d, J=11.6 Hz, 2H), 2.95 (m, 2H), 2.23 (m, 1H), 1.81 (d, J=13.2 Hz, 2H), 1.73 (m, 2H).
