Procedure

By the procedure of Example 27, except that 2.1 equivalents rather than 3.2 equivalents of triethylamine were employed, ethyl 1-(2-benzyloxy-1-naphthyl)-1-hydroxymethanecarboximidate hydrochloride (4.0 g., 0.011 mole) in 180 ml. of tetrahydrofuran was converted to toluene recrystallized 5-(2-benzyloxy-1-naphthyl)oxazolidine-2,4-dione (1.61 g., m.p. 197°-199.5° C.).

Workup

  1. customrecrystallized 5-(2-benzyloxy-1-naphthyl)oxazolidine-2,4-dione (1.61 g., m.p. 197°-199.5° C.)
