3-[4-methyl-3-oxo-7-(1-trifluoromethylvinyl)-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triazaphenanthren-6-ylamino]azetidine-1-carboxylic acid tert-butyl ester 在
钯 氢气 、
乙酸乙酯 、 petroleum ether 作用下,
以
乙酸乙酯 为溶剂,
反应 16.0h,
以to give 3-[4-methyl-3-oxo-7-(2,2,2-trifluoro-1-methyl-ethyl)-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triaza-phenanthren-6-ylamino]-azetidine-1-carboxylic acid tert-butyl ester (0.020 g, 17%)的产率得到3-[4-methyl-3-oxo-7-(2,2,2-trifluoro-1-methylethyl)-2,3,4,10-tetrahydro-9-oxa-1,2,4a-triazaphenanthren-6-ylamino]azetidine-1-carboxylic acid tert-butyl ester
