The invention relates to a pharmaceutical composition for non-hormonal, on-demand contraception and to processes for preparing this pharmaceutical composition. The latter comprises 2H-indazole as novel EP2 receptor antagonists in combination with COX inhibitors. The invention furthermore provides a method for non-hormonal female-controlled on-demand contraception where a pharmaceutical composition comprising EP2 receptor antagonists in combination with COX inhibitors is taken on demand prior to expected sexual intercourse.

The first Ni‐catalyzed Suzuki–Miyauracoupling of amides for the synthesis of widely occurring biaryl compounds through N−C amide bond activation is reported. The reaction tolerates a wide range of electron‐withdrawing, electron‐neutral, and electron‐donating substituents on both coupling partners. The reaction constitutes the first example of the Ni‐catalyzed generation of aryl electrophiles from
The first efficient synthesis of various 1,4-disubstitutedpyrido[1′,2′:1,5]pyrazolo[3,4-d]pyridazines is reported. The reactivity toward chlorine release at the C-1 and C-4 positions was investigated. SNAr and palladium-catalysed cross-coupling reactions were carried out, and conditions were optimised for each procedure. 1,4-Bis(het)aryl derivatives were obtained under a Suzuki cross-coupling procedure
