The reactions of mono-, di-, and trichloronitrobenzenes with 1-methylpyrrolidine under high pressure gave products of demethylation and ring-opening through a quaternary pyrrolidinium chloride intermediate formed by the SNAr reaction. On the other hand, the reactions with 1-methylpiperidine and 4-methylmorpholine gave only demethylation products. The selectivities of the reactions of 1-methylpyrrolidine

The reaction of p-chloronitrobenzene with N-methylpyrrolidine under highpressure gave demethylation product and ring opening products through quaternary ammonium chloride intermediate formed by the SNAr reaction. On the other hand, the reactions with N-methylpiperidine and N-methylmorpholine gave only demethylation products. The reactions of o-chloronitrobenzene and 2,4-dichloronitrobenzene with above

The nucleophilicsubstitutionreactions of aromatic halides having electron-attracting groups on ortho or para position with various primary and secondary amines were accelerated by highpressure to give the corresponding N-substituted anilines in high yields. The bulkiness of amines affects its reactivity to lower the yields of the products. Although the secondary amines are usually less reactive
The present invention relates to compounds of formula (I), wherein R, R, Ar, W, X and Z are all as defined herein. The compounds of the present invention are known to inhibit the spindle checkpoint function of Monospindle 1 (Mps1 – also known as TTK) kinases either directly or indirectly via interaction with the Mps1 kinase itself. In particular, the present invention relates to the use of these compounds as therapeutic agents for the treatment and/or prevention of proliferative diseases, such as cancer. The present invention also relates to processes for the preparation of these compounds, and to pharmaceutical compositions comprising them.
