実験手順: To a solution of 3.0 g (20 mmol) of 2,4-dichloro-pyrimidine in a 10:1 mixture of dioxane:water (220 mL) is added 3.3 g (22 mmol) of 2-hydroxy-3-methyl-phenyl boronic acid followed by 6.0 g (57 mmol) of sodium carbonate. Argon is bubbled through the solution for 15 min then 2.4 g (2.1 mmol) of tetrakis(triphenylphosphine)palladium (0) is added. The reaction is heated overnight at 100° C. then cooled to ambient temperature and filtered through diatomaceous earth. The filter pad is washed with EtOAc then placed on a new receiving flask and washed with a 1:1 mixture of MeOH:DCM. The filtrate is concentrated under reduced pressure to B-16 (1.60 g, 36.0%) Argon is bubbled through the solution for 15 min then cooled to ambient temperature filtered through diatomaceous earth The filter pad is washed with EtOAc washed with a 1:1 mixture of MeOH The filtrate is concentrated under reduced pressure to B-16 (1.60 g, 36.0%)
