Procedure
A solution of 237D (0.60 gm, 2.3 mmole) in a 5.0 N solution of HCl in methanol was left stirring at room temperature for 1 hr. This was applied onto a Phenomenex Strata-X-C 33 um cation mixed-mode polymer, flushed with methanol, and the product was eluted with a 2 N solution of ammonia in methanol. Removal of the solvents left 237E, (0.20 gm; 59% yield). 1H NMR (500 MHz, CDCl3) δ 0.87 (m, 4H) 3.21 (s, 1H) 6.27 (s, 1H) 7.16 (br s, 1H).
