참여 물질

반응 단계

To a solution of 48 mg (0.3 mmol) of 1H-indole-7-carboxylic acid and 96 mg of TBTU (0.3 mmol) in 4 ml DMF, were added 0.26 ml (1.5 mmol) of N,N-diisopropylethyl amine. After stirring for 5 min at rt, 78 mg (0.3 mmol) of (4-tert-butyl-benzyl)-[2-(tetrahydro-thiopyran-4-yl)-ethyl]-amine in 1 ml DMF were added. After stirring for 24 h at rt, the reaction mixture was diluted with 50 ml water and extracted with 2×50 ml EtOAc. The combined organic phases were washed with water and brine, dried with magnesium sulfate, filtered and concentrated in vacuo to give 134 mg (99%) of a yellow solid. MS (ISP) 435.5 (M+H)+.
