PROCEDURE
实验过程
A mixture of 9-bromo-2-pyridin-2-yl-4,5-dihydro-6-oxa-1,3a-diazabenzo[e]azulene (300 mg, 0.877 mmol), 2-(4-mercaptopiperidin-1-yl)-2-methylpropionic acid methyl ester (286 mg, 1.315 mmol), Pd2(dba)3 (40 mg, 5 mol %), XantPhos (51 mg, 10 mol %) and DIPEA (0.61 mL, 3.5 mmol) in dioxane (10 mL) was purged with nitrogen and then heated at 120° C. for 1 h using microwave irradiation. The crude reaction mixture was diluted with DCM (150 mL) and purified by column chromatography (Si-PCC, gradient 0-8% 2M NH3/MeOH in DCM) affording 2-Methyl-2-[4-(2-pyridin-2-yl-4,5-dihydro-6-oxa-1,3a-diazabenzo[e]azulen-9-ylsulfanyl)piperidin-1-yl]propionic acid methyl ester as an orange oil (0.674 g, quantitative). LCMS: RT1.88 min [M+H]+ 479.1.
