2-Amino-2-thioxoethyl 2,2-dimethylpropanoate → 1-(cyclohexyl)methyl-7-methoxy-3-{2-[(tertbutylcarbonyloxy)methyl]thiazol-4-yl}-1H-indole

Participants

Reaction Steps

2-Chloro-1-[1-(cyclohexyl)methyl-7-methoxy-1H-indol-3-yl]ethanone (0.73 g, 2.30 mmol) and 2-(tert-butylcarbonyloxy)thioacetamide (1.21 g, 6.89 mmol) were suspended in ethanol (10 ml) and the resulting mixture subjected to microwave irradiation at 150° C. for 10 min using an Emrys™ Optimizer EXP. The reaction mixture was concentrated in vacuo and the residue obtained was purified by flash column chromatography eluting with 5% (v/v) ethyl acetate in n-heptane to afford 1-(cyclohexyl)methyl-7-methoxy-3-{2-[(tertbutylcarbonyloxy)methyl]thiazol-4-yl}-1H-indole as a yellow oil (1.01 g).
