Reaction Steps

A microwave vial was charged with 2-chloromethyl-5,7-dimethyl-imidazo[1,2-a]pyrimidine hydrochloride (500 mg, 2.15 mmol), and 1,2-dichloroethane (16 mL) and argon was bubbled through the mixture. To this mixture was added 1,8-diazabicyclo[5.4.0]undec-7-ene (0.350 mL, 2.34 mmol) and triphenylphosphine (848 mg, 3.23 mmol). The vial was sealed with a crimp-on cap and the mixture was heated at 140° C. for 1 hour using a microwave synthesizer. Evaporation of volatiles afforded crude (5,7-dimethyl-imidazo[1,2-a]pyrimidin-2-ylmethyl)-triphenyl-phosphonium chloride as a dark grey solid (1.976 g) which was used without purification.
