Procedure

A solution of EXAMPLE 111B (400 mg), 1-bromo-2-(2-bromoethoxy)ethane (0.246 mL), and triethylamine (0.595 mL) in N,N-dimethylformamide (6 mL) was stirred at 70° C. for 24 hours. The solution was cooled and poured into ethyl acetate (200 mL). The solution was extracted with 3× water, washed with brine, concentrated, and chromatographed on silica gel using 10% methanol/ethyl acetate to give the pure product.
