摘要

Method A. 2-Benzylidene-4-[3-(dimethylamino) pro-pyl]-2H-l, l-benzoxazin-3 (4H)-one Hydrochloride (XI, 3). A stirred suspension of 10.3 g (0.044 mol) of I in 85 mL of Me2S0 was treated with 2.2 g (0.046 mol) of NaH (50% oil dispersion). Foaming occurred as the temperature gradually rose to 35" C. When the temperature began to drop, the mixture was warmed to 70 OC, cooled to 25" C, treated with 31 mL of a 2.2 N solution of 3- ...
