Abstract
2250 J. Org. Chem., Vol. 40, No. 15, 1975'Notes ing bath was removed, and after 10 min the reaction mixture was worked up. The resulting solid was crystallized from ethanol, yielding 0.247 g (90%) of 4c, mp 117-118', NMR 6 7.1-7.4 (m, including a sharp singlet at 7.27, 8 H), 7.5-7.8 (m, 4 H). Anal. Calcd for C&&12: m/e 274.03160. Found: m/e 274.03202.
