Reaction Steps

In 50 ml dry DMF were combined 2.10 g 4,5,5a,6-tetrahydro-3H-isoxazolo[5,4,3-kl]acridine, 2.0 g milled anhydrous K2CO3 and 1.3 ml benzylbromide. The mechanically stirred mixture was heated under nitrogen at 90° C. for 18 hours. During the first 4 hours, 1 ml benzyl bromide was added every hour as TLC analysis indicated it was being consumed. For the work-up, the mixture was poured in excess water and extracted with DCM. The DCM layer was concentrated to an oil and the oil was purified on a silica column (flash chromatography) using DCM as an eluent. The product-containing fractions were combined and concentrated to a solid. The solid was recrystallized from EtOAc/hexanes and dried in a vacuum desiccator to yield 2.10 g of product, m.p. 162°-163.5° C.
