Reaction Steps

The product of Example 191 Step 1 (0.10 g, 0.38 mmole) in 1,2-dichloroethane (5 ml) was treated with 1-(4-fluorophenyl)piperazine (0.10 g, 0.58 mmole) and stirred at ambient temperature for 15 minutes. Sodium triacetoxyborohydride (0.16 g, 0.76 mmole) was added and the reaction mixture stirred at ambient temperature for 18 hours. The mixture was diluted with dichloromethane, washed (×2) with saturated sodium hydrogen carbonate solution followed by saturated brine, dried over magnesium sulphate and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with ethyl acetate to afford the title compound; MS (ES+) m/e 357 [M+H]+. The following examples were prepared from the product of Example 191 Step 1 using the method described in Example 200.
