Reaction Steps

Intermediate 71A (0.15 g, 0.43 mmol), (0.098 g, 0.64 mmol) 4-methylazepan-4-ol hydrochloride (0.062 g, 1.15 mmol, see Helvetica Chimica Acta, 45, 1823-32, (1962)) and TEA (0.159 mL, 1.15 mmol) were mixed in dichloromethane (4 mL). The mixture was stirred at RT for 30 min and then sodium triacetoxyhydroborate (0.182 g, 0.86 mmol) was added and the mixture was stirred at RT overnight. Aqueous NaHCO3 (sat., 3 mL) and dichloromethane (3 mL) were added and the mixture was filtered through a phase separator and the solvent was removed by evaporation. The product was purified twice by preparative reverse-phase HPLC at pH 10 to give 53 mg (40%). 1H NMR (600 MHz, DMSO) δ 1.11 (s, 3H), 1.35-1.45 (m, 1H), 1.55-1.74 (m, 5H), 2.32-2.64 (m, 4H), 3.46-3.55 (m, 2H), 4.04-4.16 (m, 1H), 4.52-4.67 (m, 2H), 5.05-5.2 (m, 2H), 6.85 (d, 2H), 7.25 (d, 2H), 7.61-7.73 (m, 3H), 8.05-8.11 (m, 2H), LC purity: 96%.
