摘要

(* 5.1 g, 40 mmol) and 27 (2.0 g, 11 mmol) were mixed and heated at reflux for 60 h to give a dark oil. The volatile materials were removed by rotoevaporation giving 3.6 g of semicrystalline black solid. This solid was washed with ether (100 mL) and twice recrystallized from benzene to give tan needles: mp 188-189" C; IR 1735 cm-l (C= O); NMR (CDC13) 6 2.36 (d. 3, J= 0.7 Hz, 4-Me), 3.76 (m, 8, morpholino protons), 6.04 (d. 1, J= 07 ...
