N-乙基-2,2-二甲基丙-1-胺盐酸盐

反应条件: temp:44.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Weigh 8.7 mg [3-(2,2-dimethylpropanoyl)-6-methoxy-1H-indazol-1-yl]acetic acid, 7.7 mg HOBt, and 11.5 mg EDC into a 13×100 mm screw cap tube. Add 7.6 mg N-ethyl-2,2-dimethylpropan-1-amine hydrochloride followed by 0.5 mL DMF and 13.6 mg DIEA in that order. The mixture was stirred at 44° C. over night and purified by RP-HPLC using 50-100% MeCN gradient. The pure product fractions were pooled and lyophilized to give the title compound as white solid. LC-MS: 4.04 min. (m/Z=388.3, 410.3). purified by RP-HPLC using 50-100% MeCN gradient
