Boc protected thiomorpholine carboxylic acid (3.1g, 13mmol), HOBt (2.1g, 16mmol) and EDCI hydrochloride (3.7g, 20mmol) dissolved in DMF(20ml) was added 28% of ammonium hydroxide solution (4.5g, 130mmol) at RT. After 4h, the reaction mixture was poured into saturated water solution of NaHCO3 and diluted with EtOAc, washed with sat’d NaHCO3 and brine. The organic layer was dried (Na2S04) and concentrated. The crude product was purified by flash chromatography on silica gel with EA/Hex to give .23g of amide. 1H-NMR (400 MHz, CDCI3j delta 5.2 (d, 1 H),6.15 (br., 1 H), 5.68 (br., 1 H), 5.02(br., 1 H), 4.25 (br., 1 H), 3.16(d, 1 H), 2.8 (m, 1 H), 2.7 (t, 1 H), 2.4 (d, 1 H), 1.47 (s, 9H).
128453-98-5 4-(tert-Butoxycarbonyl)thiomorpholine-3-carboxylic acid 2756831, aThiomorpholine compound, is more and more widely used in various fields.
