The invention relates to a N-piperidin-4-yl derivative having the general Formula I or a pharmaceutically acceptable salt thereof, to pharmaceutical compositions comprising the same and to the use of said N-piperidin-4-yl derivatives for the treatment and prevention of endometriosis, for the treatment and prevention of pre-menopausal and peri-menopausal hormone-dependent breast cancer, for contraception, or for the treatment of uterine fibroids or other menstrual-related disorders.
A mild and efficient procedure was developed for the [Cp∗Rh(III)]-catalyzed, 1,2,3-triazole directed CH coupling with diazomethylene-diphosphonates. This protocol provided a step- and atom-economical protocol for CC bond formation and led to structurally diverse 2-(1,2,3-triazol-2-yl)benzyl diphosphonates in good to excellent yields.
Herein, we report an alternativeapproach to Suvorexant by ortho‐cyanation of 2‐aryl‐1,2,3‐triazole with a rhodium catalyst and N‐cyano‐N‐phenyl‐p‐toluenesulfonamide, which also provides a new protocol for the diversification of benzonitriles in moderate to good yields and tolerates many useful functional groups.
An object of the present invention is to provide to a compound and a pharmaceutical composition, which have excellent Syk-inhibitory activity. The present invention provides a nicotinamide derivative represented by the following formula (I) (wherein R
1
represents a halogen atom; R
2
represents a C
1-12
alkyl group, a C
2-12
alkenyl group, a C
2-12
alkynyl group, a C
3-8
cycloalkyl group, an aryl group, an ar-C
1-6
alkyl group or a heterocyclic group, each optionally having at least one substituent; R
3
represents an aryl group or a heterocyclic group each optionally having at least one substituent; and R
4
and R
5
each independently represent a hydrogen atom; and R
2
and R
4
may form a cyclic amino group optionally having at least one substituent together with the nitrogen atom to which they bind) or a salt thereof, and a pharmaceutical composition for use in the treatment of a Syk-related disease which comprises the nicotinamide derivative or a salt thereof.
