A mild and regioselective N-alkylation reaction of 2-pyridones in water has been developed. Tween 20 (2% w/w) was added to create a micellar system for improved solubility of starting materials, which leads to enhanced reaction rates. The protocol demonstrated a wide substrate scope with good isolated yields (40-94%) for all of the 24 examples evaluated. High regioselectivity favoring N-alkylation over O-alkylation was observed for benzyl halides (>5:1), primary alkyl halides (>6:1), and bulky and less reactive secondary alkyl halides (>2.4:1).

Page/Page column 249-250, (2008/06/13)
A pyrazole compound represented by the general formula (I) or a salt thereof which has a hepatic glycogen phosphorylase inhibitory activity and therefore is useful as a therapeutic or prophylactic agent for diabetes or a pharmacologically salt thereof : wherein the ring Q represents an aryl group or an aromatic heterocyclic group; R1 represents a hydrogen atom, a halogen atom, a C1-6 alkyl group or a C1-6 alkoxy group; R2 represents a halogen atom, a C1-6 alkyl group, a C1-6 alkoxy group or an azide group; R3 represents a halogen atom, a hydroxyl group, a C1-6 alkyl group, a halo-C1-6 alkyl group, a C1-6 alkoxy group, an azide group, an amino group, an acylamino group or a C1-6 alkylsulfonylamino group; R4 and R5 independently represent a hydrogen atom, a C1-6 alkyl group which may be substituted, a a C3-8 cycloalkyl group, a saturated heterocyclic group which may be substituted, an aryl group which may be substituted, a C7-14 aralkyl group, an aromatic heterocyclic group or the like.
