Using a method similar to Example 14, using 6-(1-oxo-indan-5-yloxy)-nicotinamide (Intermediate 4, 536 mg, 2.00 mmol), 2-cyclohexylethylamine HCl ((Synthesis (1983), (5), 388-9), 393 mg, 2.40 mmol), Et3N (243 mg, 2.40 mmol), Ti(iPrO)4 (1.14 g, 4.00 mmol), TiCl4 (11.0M/DCM, 4.00 ml, 4.00 mmol), and NaBH3CN (251 mg, 4.00 mmol) gives the title compound (628 mg) as a yellow solid. Mass spectrum (ion spray): m/z=380 (M+1); 1HNMR (CDCl3): 8.59 (s, 1H), 8.15 (d, 1H), 7.38 (d, 1H), 6.99 (s, 1H), 6.95 (d, 1H), 6.94 (d, 1H), 5.89 (br. s, 2H), 4.24 (t, 1H), 3.01 (m, 1H), 2.82 (m, 1H), 2.75 (t, 2H), 2.45 (m, 1H), 1.88 (m, 1H), 1.74-1.62 (m, 5H), 1.43 (m, 2H), 1.38-1.13 (m, 4H), 0.93 (m, 2H).
