Adding a certain compound to certain chemical reactions, such as: 683-57-8, name is 2-Bromoacetamide, belongs to amides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 683-57-8, HPLC of Formula: C2H4BrNO
A flask was charged with 4-cyano-lH-imidazole-2-carboxylic acid (2-cyclohex-l- enyl-4-piperidin-4-yl-phenyl)-amide TFA salt (50 mg, 0.10 mmol) (as prepared in Example 14, step (b)), NEt3 (32 muL, 0.23 mmol), 2-bromoacetamide (16 mg, 0.12 mmol), and 0.5 mL of DCM and stirred for 4 h at 25 0C. The reaction was concentrated and the title compound was purified by RP-EtaPLC (C 18), eluting with 30-50 % CH3CN in 0.1 % TFA/H2O over 12 min to give 42 mg (75 %) of a white solid. 1H-NMR (400 MHz, DMSO-d6): delta 14.28 (br s, IH), 9.78 (s, IH), 9.50 (br s, IH), 8.34 (s, IH), 8.00 (s, IH), 7.88 (d, IH), 7.72 (s, IH), 7.18 (dd, IH), 7.10 (d, IH), 5.76 (m, IH), 3.94 (s, 2H), 3.58 (m, 2H), 3.12 (m, 2H), 2.80 (m, IH), 2.20 (m, 4H), 1.98 (m, 4H), 1.80 (m, 4H). Mass spectrum (ESI, m/z): Calcd. for C24H28N6O2, 433.2 (M+H), found 433.2.
