Reaction Steps

A solution of p-chlorophenyl magnesium bromide (0.17 M) in ether (100 ml) was treated with a solution of 1-benzyl-1,6-dihydro-5-methoxy-3-[2H]pyridone (32.5 g, 0.25 M) in THF (150 ml). The reaction was stirred 1 hour, poured onto cold 2 N hydrochloric acid (250 ml) and stirred 30 min. Removal of the resulting precipitate by filtration, followed by air-drying and recrystallisation from methanol gave the title compound as the hydrochloride hydrate (24.1 g) m.p. 166°-8°.
