PROCEDURE
实验过程
A reaction vial was charged with 4-(2-bromo-4-(trifluoromethyl)phenyl)-N-(4-methoxybenzyl)-N-(thiazol-2-yl)-3,4-dihydro-2H-benzo[b][1,4]oxazine-7-sulfonamide (EXAMPLE 53, Step 1; 0.347 g, 0.542 mmol) and Pd(PPh3)4 (0.031 g, 0.027 mmol), and then diluted with DMF (1.084 ml). After purging with nitrogen, allyltributyltin (0.202 ml, 0.650 mmol) was added and the reaction was heated to 100° C. for 30 minutes until completion. The reaction was concentrated in vacuo and purified via silica-gel chromatography (12-g RediSep Gold column), eluting with 0-30% ethyl acetate in heptanes) to yield 4-(2-allyl-4-(trifluoromethyl)phenyl)-N-(4-methoxybenzyl)-N-(thiazol-2-yl)-3,4-dihydro-2H-benzo[b][1,4]oxazine-7-sulfonamide (0.312 g, 0.519 mmol, 96% yield) as a yellow oil. m/z (ESI) 602.1 (M+H)+.
