Reaction Steps

To 1-(6,7-dimethoxy-quinazolin-4-yl)-2,3-dihydro-1H-indol-6-ylamine (99 mg, 0.307 mmol; from Example 30) and pyridine (32 μL, 0.620 mmol) in CHCl3 (5 mL) was added acetyl chloride (33 μL, 0.455 mmol). The mixture was refluxed 2 hours, diluted with CHCl3 (15 mL), and the organic solution was washed with saturated aqueous NaHCO3, dried over Na2SO4(s), filtered and concentrated in vacuo. Flash chromatography on silica (5% MeOH/CHCl3) afforded 77 mg of product. (M.P. 223°-229° C. (dec); GC-MS: 364 (M+); anal. RP18-HPLC RT: 3.42 min.).
