81% | General procedure: A round-bottom flask was chargedwith N,N-dialkyl aniline dissolved in toluene solution, under N2 condition. TBHP was added drop wise and reaction was stirred for 2 min. Triethylamine was added thereafter, and then the contents of the reaction were stirred for 3 h at 110 C under inert N2 condition. The reaction mixture was washed 2-3 times with H2O and ethyl acetate. The upper organic layer was separated and dried over sodium sulphate and then subjected to rotavapour. The crude mixture was purified by column chromatography on silica gel (60-120). |

77% | To a solution of 3-methoxy-/V-methylaniline (137 mg, 1 mmol) in CH2CI2 (3 ml) was added NaOH 50% (1 ml) under stirring followed by tetrabutyl ammonium hydrogen sulphate (51 mg, 0.15 mmol). After few minutes, 5-bromothiophene-2-sulfonyl chloride (262 mg, 1 mmol) was added to the reaction mixture. The solution was stirred at rt for 5 h, then water (10 ml) was added to quench the reaction followed by ethyl acetate (10 ml). The aqueous layer was extracted twice with ethyl acetate. The organic layer was dried over MgS04, filtered and concentrated under reduced pressure. The product was purified on silica gel (/7-hexane/ethyl acetate 8 : 2) and afforded the desired compound as yellowish oil (277 mg, 77%); IR (cm 1) : 3101, 2938, 2835, 1734, 1602, 1354; *H NMR (CD3COCD3) : 3.27 (s, 3H), 3.77 (s, 3H), 6.78 - 6.81 (m, 2H), 6.90 - 6.92 (m, 1 H), 7.26 - 7.30 (m, 2H), 7.31 (d, J = 4.1 Hz, 1 H); 13C NMR (CD3COCD3) : 38.7, 55.8, 113.5, 114.2, 119.3, 120.1, 130.5, 132.2, 134.3, 138.9, 143.2, 161.0. | |

After few minutes, 5-bromothiophene-2-sulfonyl chloride (262mg, 1mmol) was added to the reaction mixture. The solution was stirred at room temperature for 5h. Water (10mL) was added to quench the reaction followed by EtOAc (10mL). The aqueous layer was extracted twice with EtOAc (2×15mL). The organic layer was dried over MgSO4, filtered and the solution was concentrated under reduced pressure. The product was purified on silica gel (hexanes/EtOAc 8:2) to afford the desired compound as yellow oil (277mg, 77%).
