Reaction Steps

A solution of 7-methyl-6-(5-methyl-thiophen-2-yl)-7H-pyrrolo[3,2-f]quinazoline-1,3-diamine (100 mg, 0.32 mmol) in N,N-dimethylformamide (5.0 mL) at 25° C. was treated with 60% sodium hydride (25 mg, 0.62 mmol) and iodomethane (0.62 mL, 0.35 mmol) and stirred at 25° C. for 15 min. The resulting mixture was poured into water and extracted with a 9/1 methylene chloride/methanol solution. Flash chromatography (Merck Silica gel 60, 230–400 mesh, 9:1 methylene chloride/methanol) afforded 7,N1-dimethyl-6-(5-methyl-thiophen-2-yl)-7H-pyrrolo[3,2-f]quinazoline-1,3-diamine (12 mg, 11.5%) as a light yellow solid; EI-HRMS m/e calcd for C17H17N5S (M+H)+ 324.1278, found 324.1280; and 7,N1,N1-trimethyl-6-(5-methyl-thiophen-2-yl)-7H-pyrrolo[3,2-f]quinazoline-1,3-diamine (18 mg, 16.5%) as a dark brown solid; EI-HRMS m/e calcd for C18H19N5S (M+H)+ 338.1434, found 338.1437.
