Sodium borohydride → (+/-)-6-[(4-chlorophenyl)hydroxymethyl]-1-methyl-4-(3-propoxyphenyl)-2(1H)-quinolinone

Participants

Reaction Steps

A solution of interm. (7-i) (3.55 g) in methanol (20 ml) and THF (20 ml) was cooled. Sodium borohydride (0.37 g) was added portionwise. The mixture was stirred at room temperature for 30 minutes, hydrolized and extracted with DCM. The organic layer was separated, dried (MgSO4), filtered and the solvent was evaporated till dryness, yielding 3.5 g (100%) of (±)-6-[(4-chlorophenyl)hydroxymethyl]-1-methyl-4-(3-propoxyphenyl)-2(1H)-quinolinone (interm. 7-j).
