Reaction Steps

This compound was prepared as described for Example 2, using (2R)-4-bromobenzenesulfonic acid 8-methyl-2,3-dihydro-[1,4]dioxino[2,3-f]quinolin-2-ylmethyl ester (0.22 g, 4.9 mmol), 6-fluoro-3-piperidin-3-ylmethyl-1H-indole (0.13 g, 5.9 mmol), to afford 0.11 g (50%) of the (S)-enantiomer of the title compound as a light brown oil. The hydrogen chloride salt was prepared in ethyl acetate and collected as 0.12 g of a yellow solid, m.p. 50° C. (dec).
