Participants

Reaction Steps

3 Grams of 3-hydroxymethylcarbostyril was suspended in 100 ml of chloroform, then a solution containing 2 g of thinyl chloride in 20 ml of chloroform was added dropwise thereto at a room temperature with stirring condition. The reaction mixture was further sitrred at a room temperature for 1 hour. The reaction mixture was concentrated under a reduced pressure, and the residue obtained was recrystallized from methanol to obtain 2.9 g of 3-chloromethylcarbostyril in the form of colorless needle-like crystals.
