Reaction Steps

A procedure similar to that used to prepare compound 158 was used except that (S)-2-((S)-2-methyl-heptyl)-succinic acid 4-tert-butyl ester 166 (5.78 g, 20.18 mmol) was used as a reactant to give 167 as an oil (4.18 g, 76%). 1H NMR (400 MHz, CDCl3) δ 3.64–3.58 (m, 1H), 3.84–3.42 (m, 1H), 2.28–2.20 (m, 1H), 2.09–2.02 (m, 1H), 1.43 (s, 9H), 1.26–1.18 (m, 8H), 1.11–1.04 (m, 2H), 0.87–0.83 (m, 6H); MS (APCI) m/z 217 (M+−55, 50%, −tBu).
