complexes with danglingfunctionalorganicgroups were synthesized by reaction of zinc acetate with a series of bifunctional p-substituted benzene derivatives (a combination of carboxylate, oximate, amino, β-ketoimine, and salicylaldime groups). Selective coordination to carboxylate groups was observed when the second functionalgroup was an oxime or β-ketoimine group. When the second group was an amine

The novel non-hygroscopic crystals of p-aminomethylbenzoic acid can be obtained by heating hygroscopic crystals of p-aminomethylbenzoic acid while keeping the hygroscopic crystals in contact with moisture to transform the hygroscopic crystals to non-hygroscopic crystals.
The non-hygroscopic crystals of p-aminomethylbenzoic acid can be particularly advantageously handled in the atmosphere as compared with the conventional hygroscopic crystals. Especially when the p-aminomethylbenzoic acid is used for the non-aqueous reaction, the crystals of the invention are exceptionally advantageous from the viewpoints of removal of moisture and humidity control.
The present invention relates to compounds of formula (I): or pharmaceutically acceptable salts or mixture thereof that inhibit serine protease activity, particularly the activity of hepatitis C virus NS3-NS4A protease.
