Procedure

To a solution of (2-chloro-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine (50 mg, 0.167 mmol) in 2 ml methanol was added sodium methoxide (500 μl, 25% by wt. in methanol). The solution was stirred at 80° C. for 1 h, and it was diluted with 50 ml ethylacetate. The solution was washed with water, dried and concentrated. The product was purified using small silica column and isolated as off white solid (22 mg, 54%). 1H NMR (CDCl3): 7.89 (d, J=8.4 Hz, 1H), 7.53 (ddd, J=8.7, 5.4 and 2.4 Hz, 1H), 7.19-7.14 (m, 2H), 6.99-6.93 (m, 2H), 6.90-6.85 (m, 2H), 4.14 (s, 3H), 3.86 (s, 3H), 3.64 (s, 3H).
