thiomorpholine-4-carbonyl chloride

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

Procedure: In analogy to example 1, 200 mg (1.315 mmol) of 6-fluoro-1H-indazol-3-ol were reacted with 261.4 mg (1.578 mmol) of thiomorpholine-4-carbonyl chloride. Yield: 39 mg (7%), M+H+: 411.17.

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: N-t-Butoxycarbonyl-N,N'-dimethylethylenediamine (200 mg) was added to a solution of thiomorpholinocarbonyl chloride (228 mg) and triethylamine (123 mg) in methylene chloride (10 ml) which was cooled at 0° C. The mixture was stirred at ambient temperature for 20 minutes and the solvent was evaporated in vacuo. The residue was dissolved in ethyl acetate and the solution was washed with 0.6N hydrochloric acid, water, saturated sodium bicarbonate solution, and saturated sodium chloride solution successively, dried over magnesium sulfate, and concentrated under reduced pressure to give N-t-butoxycarbonyl-N'-thiomorpholinocarbonyl-N,N'-dimethylethylenediamine (376 mg) as an oil. Rf: 0.43 (chloroform:methanol, 10:1, V/V) the solvent was evaporated in vacuo The residue was dissolved in ethyl acetate the solution was washed with 0.6N hydrochloric acid, water, saturated sodium bicarbonate solution, and saturated sodium chloride solution successively dried over magnesium sulfate concentrated under reduced pressure

Procedure: A solution of 10 g (97 mmol) of thiomorpholine in 200 ml of toluene is added dropwise at 0° to a solution of 85 ml (165 mmol) of 20% phosgene in toluene and the white suspension is stirred for 1 h at RT. Excess phosgene is driven off by introducing nitrogen, the suspension is filtered, and the filtrate is concentrated by evaporation. The title compound is obtained in the form of a yellow oil. IR (CH2Cl2, cm-1): 1735, 1450, 1440, 1405, 1370, 1290, 1180. by introducing nitrogen the suspension is filtered the filtrate is concentrated by evaporation
