Reaction Steps
To a vial charged with 7-bromo-4-chloro-8-methylquinoline (0.950 g, 3.70 mmol) was added Dioxane (14.81 ml), DIEA (1.294 ml, 7.41 mmol), xantphos (0.429 g, 0.741 mmol), Pd2(dba)3 (0.339 g, 0.370 mmol) and benzyl mercaptan (0.438 ml, 3.70 mmol). The vessel was sealed and heated to 110° C. for 3 hr affording complete conversion according to LC-MS. The mixture was filtered through Celite and dried under reduced pressure and purified with a 25 g Interchim column ramping EtOAc in heptane (0-50%, 10% DCM throughout) affording product as a yellow oil as a mixture of mono and bis substituted product according to MS as one LC peak, 7-(benzylthio)-4-chloro-8-methylquinoline (1.100 g, 3.67 mmol, 99% yield). m/z (ESI) 300.2 (M+H)+.
