Participants

Reaction Steps

Alternatively, the compound of Example 3 was prepared by the Grignard reaction of n-butylmagnesium chloride with excess benzyloxalate to obtain desired product in 27% yield. 1H NMR (CDCl3, TMS) δ0.91 (t,3H), 1.35 (m,2H), 1.6 (m,2H), 2.85 (t,2H), 5.29 (s,2H), 7.4 (m,5H). Rf value is identical to Example 3.
