Reaction Steps

A stirred mixture of 4'-[(6-hydroxyhexyl)-methylamino]-4-methylsulfonylstilbene (App-Ex. 4, 20.0 g, 52 mmol), triethylamine (6.3 g, 62 mmol) and dry dichloromethane (DCM) was treated dropwise with acryloyl chloride (5.6 g, 62 mmol) in 50 mL of DCM at 23° C. under nitrogen. The resulting solution was stirred at 23° C. for 72 hours, and then filtered. The filtrate was washed successively with saturated NaCl, with saturated NHCO3, and with water. The organic layer was dried (MgSO4), and the solvent was removed at reduced pressure to deposit a yellow oil which gradually crystallized. The product was recrystallized from tetrahydrofuran (THF)/hexanes to yield 15.5 g (68%) of a yellow solid, mp 88°-90° C.
