The reaction can be carried out with either diethylamine or triethylamine. Aryl bromides couple at elevated temperatures (70° C.) and aryl iodides couple at room temperature. The phenol is deprotected, as shown in Scheme I, Step 3, using HCl-acetone to give the phenol of formula (12). ...
The invention relates to N-(3-amino-2-hydroxy-propyl)-aryl-, heteroaryl-, cycloalkyl- and heterocyclyl-alkylamide compounds and such compounds that are useful for the treatment of Alzheimer's disease. More specifically, the invention relates to such compounds that are capable of inhibiting beta...
-tetrahydrothabaine of formula 17 which is demethylated by treatment with potassium hydroxide in one pot at 210 c to give 6, 14-endcathano-7-(2-hydroxy-2-methyl-2-ter-butyl) -tetra-hydrotha-roripavine of formula 18 which on treatment with cyclopropyl-methyl bromide gives the compound N...
Thus, it seems that this structure contains 1.5 bromide anions per molecule with the protonated piperazine nitrogen atom N11 and the half-protonated nitrogen atom N25, which ensures that charge balance is preserved. Hence, the crystal structure is a 1:1 mixture of mono-cations and di-cations of...
As can be seen in Figure 2, five-day treatment with ADS-531 did not influence food intake by the rats, whereas treatment with ciproxifan caused a significant decrease in consumption. It is important to note that the treatment was preceded by an adaptive period to experimental conditions. Figu...
