这些化合物可以用各种方法制备。最普通的二种制备方法说明如下：
Figure C9719278600281
方法A。将羧酸以各种方法与胺HN(R5)R4连结。常用的方法是偶合方法，如肽化学上所用的方法。以几乎等量的偶合剂，如TBTU,DCCI/HOBt,CDI，等，加到偶合参与者(coupling partners)中。适宜的溶剂是DMF,THF,CH2Cl2,CHCl3，乙腈其他惰性溶剂或其混合物。适宜的温度是-50℃至+120℃，较佳是0℃到40℃。
也可先将羧酸按已知方法使用SOCl2,SO2Cl2,PCl3,PCl5或PBr3,或其混合物转化成相应的酰基卤化物，使酰基卤化物与胺HN(R5)R4在惰性溶剂，如CH2Cl2,THF或二噁烷中于-50℃至+100℃，一般是0℃至20℃温度下进行反应。
另一方法是先将羧酸用已知方法转化成烷基酯，一般是甲基酯，然后将该酯与胺HN(R5)R4在惰性溶剂，如DMF，二噁烷或THF中进行反应。反应温度是20℃至150℃，一般是50℃至120℃。此反应也可在加压容器内进行。方法B．本方法是将按已知方法制得的α-卤基-芳基乙酰胺衍生物与胺R1(R2)NH在卤化氢的裂解下进行反应。使用无机碱，如K2CO3，NaHCO3或CaCO3，或有机碱，如三乙基胺，亨尼格(Hunig)碱，吡啶或DMAP，也可使用过量的胺R1(R2)NH清除裂解的(或过多的)卤化氢。使用DMF,THF，二噁烷或其他惰性溶剂。反应温度是0℃至100℃，一般是10℃至80℃。方法C．本发明化合物，其中R5不是H，也可如下制备：首先，按方法A或B合成R5是H的对应化合物。然后，以下方法进行N-烷基化，引入烷基，环烷基或CH2COOH。根据本发明R5是H的化合物用等当量的NaH，NaNH2,KOH,NaOCH3或其他强碱进行去质子化。该反应使用无水惰性溶剂，如THF，二噁烷或二乙基醚。然后缓慢加入对应卤化物，甲苯磺酸酯或甲磺酸酯形式的烷基化剂。该反应是在-50℃至+100℃，一般是0℃至+50℃进行。
