摘要:
The invention relates to a process for preparing 4-trifluoromethyl methoxyacetophenone comprising: (a) reacting the compound of Formula XIII with the compound of formula XIX to form the product of formula XX: and (b) hydrolyzing the compound of formula XX to 4-trifluoromethyl methoxyacetophenone:
摘要:
The invention relates to a process for selectively preparing a mono-4-protected 2-methylpiperazine from its corresponding 2-methylpiperazine in high yields, said process comprising reacting said 2-methylpiperazine with about a molar equivalent of a protecting reagent in a solvent, with the reaction being catalyzed by an acid catalyst or a base catalyst.
