Reaction Steps

Using analogous conditions and workup as described for the preparation of I-24a above, 1-(bromomethyl)-4-(trifluoromethoxy)benzene (5 g, 19.607 mmol) in DMSO (30 mL) was reacted with NaCN (1.44 g, 35.1864 mmol). The resulting mixture was stirred at 90° C. for 1 hour to afford 3.8 g of the product (95% yield). 1H NMR (300 MHz, CDCl3): 7.45-7.20 (m, 4H), 3.8 (s, 2H)
