Reaction Steps

tert-Butyl 4-[2-(pyrimidin-4(3 H)-on-5-yl)ethyl]benzoate (0.6 g,) was dissolved in N,N-dimethylaniline (5 ml) and treated with phosphorous-oxy-chloride (1.53 g 10 mmol). The reaction was heated to 100° C. for 2.5 hours and then evaporated at reduced pressure. The residue was diluted with EtOAc, washed (1N HCl 2×, H2O, saturated brine), dried over MgSO4 and evaporated to give tert-butyl 4-[2-(4-chloropyrimidin-5-yl)ethyl]benzoate as a brown oil (0.5 g, 64%) which was used without further purification.
