Conditions

Temperature: 130 °C

Procedure

In a 15 ml sealed pressure tube, was dissolved 4-chloro-N-(4-(7-methoxy-1,5-naphthyridin-4-ylthio)phenyl)phthalazin-1-amine (150 mg, 490 μmol) in 0.8 ml of DMSO. Sodium cyanide (72 mg, 1469 μmol) was added and the reaction was capped and stirred at 130° C. for 3 hours. The reaction was cooled to RT and purified via Gilson Reverse Phase HPLC eluting with a 12-75% gradient of ACN in water with 0.1% TFA. The product fractions were basified with saturated sodium bicarbonate and extracted into DCM. The DCM layers were dried over Na2SO4, filtered and concentrated in vacuo to afford 4-(4-(7-methoxy-1,5-naphthyridin-4-ylthio)phenylamino)phthalazine 1-carbonitrile. MS: [M+H]=437.
