Versuchsvorschrift

A large excess of aqueous methylamine was added to a suspension of dibenzo[b,d]thiophene-2-sulfonyl chloride (2.83 g) in sulfolane (15 ml) and the mixture was stirred at RT for 3 h. The reaction mixture was diluted with water, and the precipitate was recovered, washed with water, dried and purified by silica gel chromatography eluting with a gradient of ethyl acetate:DCM of 0:100 to 10:90 to give the title compound (1.79 g, 64%).
