Participants

Reaction Steps

In a small microwave vial with a stir bar, 2-Methoxy-ethylamine (0.1 mmol, 75 mg) is dissolved in 1 mL DMF. To this solution is added sodium hydride (60% suspension in mineral oil) (0.1 mmol, 4 mg) and the mixture is stirred at rt for 5 min. and then 1-(4-Amino-8-fluoro-quinazolin-7-yl)-3,6,6-trimethyl-1,5,6,7-tetrahydro-indol-4-one (0.044 mmol, 15 mg) is added. The reaction is sealed and placed in the microwave reactor where it is heated to 150° C. for 30 min. The reaction is cooled and quenched by pouring into 10 mL of Sat'd. NH4Cl aq. and extracted 3 times with 2 mL CH2Cl2. The combined organics are dried with Na2SO4, concentrated, and purified by silica gel chromatography on Biotage using a gradient of 0-50% MeOH in CH2Cl2. 1-[4-Amino-8-(2-methoxy-ethylamino)-quinazolin-7-yl]-3,6,6-trimethyl-1,5,6,7-tetrahydro-indol-4-one is isolated (8 mg, LC/MS m/z=393 [M+H]+) as a tan powder.
