Reaction Steps

A mixture of 2,4-dichloro-quinazoline (88 wt %, 525 mg, 2.3 mmol), (2-methoxy-benzyl)-methyl-amine (300 μL, 2.01 mmol) and 1 drop of concd HCl in i-PrOH (8 mL) was reacted for 5 days then concd in vacuo. Satd NaHCO3 (5 mL) was added then the product extracted into CHCl3 (2×4 mL). The organic portion was washed with water (1×3 mL) then dried (MgSO4), filtered through a plug of silica with an EtOAc wash then purified by MPLC (SiO2/0-20% i-PrOH in CHCl3) yielding the title compound as a white solid (247 mg; 39%). 1H NMR (CDCl3) δ 7.83-7.77 (m, 2H), 7.67 (m, 1H), 7.40-7.32 (m, 2H), 7.26 (m, 1H), 7.01 (m, 1H), 6.95 (m, 1H), 4.96 (s, 2H), 3.81 (s, 3H), 3.31 (s, 3H); LC-MS (ESI+; 314 ([M+H]+)).
