The present invention provides compounds of Formula (I): as defined in the specification and compositions comprising any of such novel compounds. These compounds are antagonists of Ρ2Y1 receptor and may be used as medicaments in the treatment and/or prophylaxis of thromboembolic disorders.
A method for producing a pyrazole compound represented by formula (1):
(wherein R
1
represents an optionally substituted C
1-12
alkyl group, an optionally substituted C
3-12
cycloalkyl group, an optionally substituted C
6-16
aryl group, or an optionally substituted pyridyl group, R
2
and R
3
each independently represent a hydrogen atom, a halogen atom, a C
1-3
alkyl group, or a C
1-3
haloalkyl group), said method including a step in which a pyrazolidine compound represented by formula (2):
(wherein R
1
, R
2
, and R
3
are as defined above)
is reacted with a nitrite in the presence of an acid,
allows a pyrazole compound to be produced industrially.
2-halobenzonitriles is presented. The reaction proceeds through a domino reaction sequence, consisting of a regioselective palladium-catalyzed coupling of monosubstituted hydrazines with 2-halobenzonitriles, followed by an intramolecular hydroamination through a 5-exo-dig cyclization and subsequent isomerization to directly afford a wide variety of substituted 2H-indazole analogues in good to excellent yields
