Oxalyl chloride → HCID 15858574, compound

Participants

Reaction Steps

13 ml of oxalyl chloride were added at ambient temperature to a solution of 23 g of the product of Stage C and 230 ml of chloroform and the mixture was stirred for three hours at ambient temperature, and concentrated under reduced pressure by proceeding with two entrainments with cyclohexane to obtain 28 g of crude product which was crystallized from a mixture of 50 ml of cyclohexane and 50 ml of diisopropyl ether after partial concentration. Separation was carried out, followed by washing with diisopropyl ether and drying under reduced pressure to obtain 16.24 g of the expected product melting at 93° C.
