N,N-dimethyl-3-sulfanylbenzamide

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A stirred mixture of Intermediate 63 (0.4 g), Intermediate 28 (0.16 g) and potassium carbonate (0.38 g) in 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (10 ml) was heated at 100° C. under nitrogen for 3 h. A further portion of Intermediate 28 (0.07 g) was added and the mixture stirred at 60° C. for 23 h. The cooled mixture was diluted with water (100 ml) and extracted with ethyl acetate (3×100 ml). The combined organic extracts were washed with water (2×70 ml) and brine (70 ml), dried over magnesium sulphate and concentrated in vacuo. The residue was purified by chromatography on silica gel eluting with methanol followed by mass directed preparative HPLC (Method A) to give the title compound as a yellow foam (0.12 g). extracted with ethyl acetate (3×100 ml) The combined organic extracts were washed with water (2×70 ml) and brine (70 ml) dried over magnesium sulphate concentrated in vacuo The residue was purified by chromatography on silica gel eluting with methanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Iodine (1 g) was added to a stirred solution of 3-[(dimethylamino)carbonylbenzenesulfonyl chloride (2 g) (Borthwick et al, J. Med. Chem 2002, 45(1), 1-18) and triphenylphosphine (8.4 g) in 1,4-dioxane at 0° C. The mixture was stirred for 0.5 h at ambient temperature. The mixture was poured into a sodium sulphite solution (50 ml), extracted into ethyl acetate (2×30 ml) and washed with 2N sodium hydroxide solution (2×40 ml). The alkaline extracts were acidified and re-extracted into dichloromethane (3×50 ml). The extracts were washed with water (100 ml), dried (Na2SO4) and evaporated to give the title compound as a colourless solid (1.1 g). extracted into ethyl acetate (2×30 ml) washed with 2N sodium hydroxide solution (2×40 ml) re-extracted into dichloromethane (3×50 ml) The extracts were washed with water (100 ml) dried (Na2SO4) evaporated
