Butanethiol → HCID 25061237, compound

Participants

Reaction Steps

In a small microwave vial with a stir bar, butanethiol (0.494 mmol, 44.56 mg) is dissolved in 3 mL DMF. To this solution is added NaH (60% suspension in mineral oil) (0.494 mmol, 20 mg) and the mixture is stirred at rt for 5 minutes and then 1-(4-Amino-5-fluoro-quinazolin-7-yl)-3,6,6-trimethyl-1,5,6,7-tetrahydro-indol-4-one (0.0988 mmol, 33.4 mg) is added. The reaction is sealed and placed in the microwave reactor where it is heated to 120° C. for 30 min. The reaction is cooled and quenched by pouring into 30 ml sat. NH4Cl aq. and extracted 3 times with 10 mL EtOAc. The combined organics are dried with Na2SO4, concentrated, and purified by silica gel chromatography on Biotage using a gradient of 0-20% MeOH in DCM. 1-(4-Amino-5-butylsulfanyl-quinazolin-7-yl)-3,6,6-trimethyl-1,5,6,7-tetrahydro-indol-4-one is isolated (22.1 mg, LC/MS m/z=409 [M+H]+) as a yellow powder.
