実験手順
To a magnetically stirred, 25° C. solution of 2.3 g (0.006 mol) of product of Step A and 0.71 g (0.007 mol) of triethylamine in 40 ml of DMF was added dropwise 0.38 g (0.007 mol) of cyclopropylamine. After 18 hours the reaction mixture was poured into H2O and extracted with diethyl ether. The ether phase was washed with H2O, and dried (MgSO4). The dry ether phase was concentrated in vacuo to 1.95 g of a brown solid. The crude was recrystallized from hexane/EtOAc affording 1.2 g (50%) of product as a beige solid; mp 111°-112° C.
