Reaction Steps

Using a similar protocol as described in Example 10 employing 29D (0.10 g, 0.36 mmol) and ethyl 5-phenyl-1,3,4-oxadiazole-2-carboxylate (0.10 g, 0.46 mmol) as starting materials afforded 67 mg (41%) of 29 as a foam. 1H NMR (500 MHz, DMSO-d6): δ 2.10 (s, 3H), 2.12-2.50 (bm, 8H), 3.43 (s, 2H), 4.05-4.16 (m, 1H), 4.50-4.70 (m, 2H), 5.03-5.23 (m, 2H), 6.68-6.84 (m, 2H), 7.25-7.37 (m, 1H), 7.57-7.75 (m, 3H), 8.00-8.13 (m, 2H), MS (APCI+) m/z 452 [M+H]+, LC purity: 97%.
