Versuchsvorschrift

A solution of m-chlorophenyl magnesium bromide (85 mM) in ether (50 ml) was treated dropwise with a solution of 1-benzyl-1,6-dihydro-5-methoxy-3-[2H]pyridone (16.3 g, 75 mM) in THF (75 ml) and stirred 1 hour. The reaction mixture was poured onto cold 2 N hydrochloric acid (150 ml) and stirred 30 min. Removal of the resulting precipitate by filtration, followed by air-drying and recrystallisation from ethanol gave the title compound as the hydrochloride hydrate (14.7 g) m.p. 143°-5°.
