Using a method similar to Example 1, using 6-(1-oxo-indan-5-yloxy)-nicotinamide (Intermediate 4, 268 mg, 1.00 mmol), 2-thiopheneethylamine (152 mg, 1.20 mmol), Ti(iPrO)4 (568 mg, 2.00 mmol), TiCl4 (1.0M/DCM, 2.00 ml, 2.00 mmol), and NaBH3CN (125 mg, 2.00 mmol) gives the title compound (196 mg) as a white solid. Mass spectrum (ion spray): m/z=380 (M+1); 1HNMR (CDCl3): 8.58 (s, 1H), 8.15 (d, 1H), 7.35 (d, 1H), 7.16 (d, 1H); 6.99 (s, 1H), 6.96-6.93 (m, 3H), 6.86 (d, 1H), 5.81 (br. s, 2H), 4.28 (t, 1H), 3.11-2.96 (m, 5H), 2.83 (m, 1H), 2.46 (m, 1H), 1.87 (m, 1H).
