A water-based biphasic reaction process has been developed for conducting exothermic reactions without organic solvents. This procedure is rapid, simple, and suitable for small scale synthesis as well as larger (multi-molar) scale reactions. The preparation of several hundred grams of clofibric acid and analogues by this eco-friendly and energy-efficient procedure is described. Smaller amounts of these compounds were prepared by the friction-activated 'Grindstone Chemistry' method described previously.

Paragraph 000225, (2014/11/13)
The invention provides a compound of structure Ar1-Ar2-X-C(R1R2)-C(=O)-N(R3)-Ar3-Ar4 for modulating WNT activity. In this structure, Ar1, Ar2, Ar3 and Ar4 are, independently, optionally substituted aryl or heteroaryl groups; R1 and R3 are, independently, H or optionally substituted alkyl groups; R2 is H or an optionally substituted alkyl group or an alkylene group which, together with the carbon atom to which it is attached and X, forms a non-aromatic ring or an alkylene group which, together with the carbon atom to which it is attached and X and two adjacent atoms of Ar2, forms a non-aromatic ring; X is O, CR4R5, N or NR4, wherein if X is N, it is bonded to R2; R4 is H, optionally substituted alkyl or an alkylene chain, optionally containing a heteroatom and/or a carbonyl group, which, together with the C or N to which it is attached and two adjacent atoms of Ar2, forms a non-aromatic ring; R5 is H, NH2 or an optionally substituted alkyl group.
