Acryloyl chloride benzene reaction

In the case of theophylline, the reaction of acryloyl chloride or methacryloyl with theophylline in dry benzene gave acryloyltheophylline (AThe) or metha-cryloyltheophylline (MAThe) at room temperature after 12 h in the presence of triethylamine in 75% and 65% yield, respectively. 

Aza-annulation with unsymmetrical p-diketone 156 resulted in regioselective generation of 157, which gave 158 upon reaction with acryloyl chloride in benzene (47%) or THF (96%) (eq. 33) 56.57,59 xhe reaction of cinnamoyl chloride with 157 in benzene gave 158 in 30% yield.56...
