Reaction Steps
To 4-(6-chloro-2,3-dihydro-indol-1-yl)-quinazolin-7-ol (125 mg, 0.42 mmol; from Example 65) in DMF (2 mL) was added H2O (50 μL), K2 CO3 (s) (116 mg, 0.84 mmol) and tetramethylammonium hydroxide pentahydrate (15 mg, 0.08 mmol) followed by 3-bromopropanol (43 μL, 0.46 mmol). The mixture was stirred at 50° C. under N2(g) for 24 hours before another aliquot (11 μL) of 3-bromopropanol was added. After heating another 24 hours, extractive workup and chromatography analogous to that described in Example 1 followed by conversion to the HCl salt as outlined for Example 2 afforded 119 mg (70%) of product. (M.P. 211°-223° C. (dec); LC-MS: 356 (MH+); anal. RP18-HPLC RT: 4.40 min.; M.P. of free-base: 137°-138° C.).
