Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 39093-93-1, name is Thiomorpholine 1,1-dioxide. This compound has unique chemical properties. The synthetic route is as follows. 39093-93-1
Example 5; l-(5-tert-Butyl-3-(thiomorpholine-l,l-dioxide-4-carbonyl)thiophen-2-yl)-3-(4-(2- (methylcarbamoyl)pyridin-4-yloxy)phenyl)urea [0228] To a solution of 6-tert-butyl-l/f-thieno[2,3-cTj[l,3]oxazine-2,4-dione (3.7 g, 15 mmol) in dioxane (30 mL) was added 4-(4-aminophenoxy)-N-methylpicolinamide (3.4 g, 14 mmol), and the reaction mixture was heated at 90 0C for 4 h. The volatiles were evaporated under reduced pressure to give the crude product which was used in the next step without further purification. EPO [0229] To a solution of 5-tert-butyl-2-(3-(4-(rhoyridin-4-yloxy)rhohenyl)ureido)thiorhohene-3- carboxylic acid (ca 14 mmol) in THF (70 mL) were added thiomorpholine 1,1 -dioxide (2.27 g, 16.8 mmol, 1.2 eq), HOBt (2.08 g, 15,4 mmol, 1.1 eq), EDCI (3.22 g, 16.8 mmol, 1.2 eq), and the mixture was stirred at room temperature for 16 h. The volatiles were evaporated under reduced pressure to give the crude product which was extracted with saturated sodium bicarbonate (3 x 40 mL) and ethyl acetate (150 mL). The organic layer was dried and diluted with ethanol (40 mL). Upon concentration of the solution using rotary evaporator, precipitation of solid occurred. The solid was digested with ethanol (70 mL), filtered, washed with ethanol to give the product which was dried under vacuum at 70 0C for 24 h. (yield = 7.2 g, 82percent). 1H NMR (400 MHz, DMSOd6) delta 9.89 (s, IH), 9.63 (s, IH), 8.73 (m, IH), 8.47 (d, J = 6.8 Hz, IH), 7.54 (d, J = 8.8 Hz, 2H), 7.35 (d, J = 2.8 Hz, IH), 7.13 (d, J = 8.8 Hz, 2H), 7.11 (m, IHO, 6.65 (s, IH), 3.93 (m, 4H), 3.27 (m, 4H), 2.75 (d, J = 5.2 Hz3 3H), 1.30 (s, 9H).
