Procedure

A solution of the hydrochloride salt of 3-[({4-[(3-chloro-2-fluorophenyl)amino]-7-methoxyquinazolin-6-yl}methyl)(methyl)amino]azetidine-3-carboxamide (100 mg, 0.19 mmol Example 74), diisopropylethylamine (100 μl, 0.58 mmol), 2-chloroethanol (60 μl, 0.58 mmol) and potassium iodide (32 mg, 0.19 mmol) in acetonitrile (1.5 ml) was heated in a microwave at 160° C. for 20 minutes. Purification of the resulting product on preparative HPLC (standard basic condition) gave the title product (10 mg, 11%) as a white solid; 1H NMR Spectrum: (CDCl3) 2.40 (s, 3H), 2.75 (t, 2H), 3.47 (s, 2H), 3.61 (t, 2H), 3.70 (s, 2H), 3.93 (s, 3H), 3.93 (s, 2H), 5.41 (brs, 1H), 6.79 (brs, 1H), 7.18 (m, 2H), 7.21 (s, 1H), 7.75 (brs, 1H), 7.86 (s, 1H), 8.52 (brs, 1H), 8.74 (s, 1H); Mass Spectrum: (M+H)+ 489.
