YieldReaction ConditionsOperation in experiment
67% With potassium phosphate; tris-(dibenzylideneacetone)dipalladium(0); tricyclohexylphosphine; In 1,4-dioxane; water; at 125℃; for 0.5h;Microwave irradiation; Inert atmosphere; Compound 31b was prepared according to the procedure reported in step-3 of Scheme- 1 from ethyl 4-chlorothieno[3,2-d]pyrimidine-2-carboxylate (31a) (350 mg, 1.44 mmol; CASNo. 319442-18-7) in dioxane (3 mL) using (3 -(((tert- butoxycarbonyl)amino)methyl)phenyl)boronic acid (Id) (543 mg, 2.16 mmol), tripotassium phosphate (0.82 mL, 2.452 mmol, 3 M aqueous solution), tricyclohexylphosphine (81 mg, 0.288 mmol) and Pd2(dba)3 (73 mg, 0.079 mmol) in argon atmosphere and heating at 125 C for 30 min in a microwave. This gave after workup and purification by flash column chromatography [silica (12 g), eluting with EtOAc in hexane from 0-70%] ethyl 4-(3-(((tert- butoxycarbonyl)amino)methyl)phenyl)thieno[3,2-d]pyrimidine-2-carboxylate (31b) (400 mg, 67 % yield) as a yellow solid.
