Reaction Conditions

Reaction Steps

A mixture of compound tert-butyl 2-methyl-1-(3-(tosyloxy)butan-2-yl)-1H-indole-3-carboxylate (200 mg, 0.43 mmol) in N,N-dimethyl formamide (2 mL) was added sodium methanethiolate (994 mg, 1.44 mmol). The reaction mixture was stirred at 110° C. for 4 hours. The reaction was quenched by adding water (6 mL). The aqueous layer was extracted with ethyl acetate (30 mL×3), and the organic layer was concentrated. The crude product was purified by preparative TLC (elute: petroleum/ethyl acetate:5:1) to give product tert-butyl 2-methyl-1-(3-(methylthio)butan-2-yl)-1H-indole-3-carboxylate (100 mg, yield: 68%). LRMS (M+H+) m/z: calc'd 333.18. found 334.
