A process for synthesis of a compound of Formula (X) wherein R1 is an aryl group substituted with one to three substituent groups, wherein each substituent group of R1 is independently C1-C5 alkyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, halogen, carboxy, cyano, or trifluoromethyl, wherein each substituent group of R1 is optionally independently substituted with one to three substituents selected from C1-C3 alkyl, C1-C3 alkoxy, phenyl, and alkoxyphenyl; and R2 and R3 are each independently C1-C5 alkyl.
一种合成化合物(X)的方法,其中R1是芳基,其上取代有一到三个取代基,R1的每个取代基可以独立地是C1-C5烷基、氨基甲酰基、烷基氨基甲酰基、二烷基氨基甲酰基、卤素、羧基、氰基或三氟甲基,R1的每个取代基可以选择性地独立地被一到三个取代基取代,这些取代基来自于C1-C3烷基、C1-C3烷氧基、苯基和烷氧基苯基;R2和R3分别独立地是C1-C5烷基。
