2-{4-[(4-Methoxy-phenyl)-methyl-amino]-quinazolin-2-ylmethyl}-isoindole-1,3-dione: A suspension of (2-chloromethyl-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine hydrochloride (10.367 g, 16.2 mmol) and K2CO3 (2.25 g, 16.3 mmol) in DMF (50 mL) was heated to 70° C. for 1 h. The reaction was cooled to rt, potassium phthalimide (6.004 g, 32.5 mmol) was added and the reaction heated to 70° C. for 2 h. The reaction was cooled to rt, diluted with EtOAc, washed with H2O and 5% NaOH, dried (MgSO4), filtered and concentrated. The residue was purified by gradient MPLC (SiO2, EtOAc/hexanes 0-100%) to yield 8.56 g (68%) of the title compound. 1H NMR (DMSO-d6) δ 7.95-8.02 (m, 2H), 7.87-7.94 (m, 2H), 7.55-7.60 (m, 2H), 7.18-7.22 (m, 2H), 7.02-7.12 (m, 1H), 6.94-7.01 (m, 2H), 6.88 (dt, 1H), 4.95 (s, 2H), 3.77 (s, 3H), 3.26 (s, 3H); HRMS (ES) calcd for C25H21N4O3 (M+H) 425.1608, found 425.1604.
