Reaction Steps

The procedure was the same as that used for the synthesis of 7a except that 500 mg (0.0015 mol) of 2 was used and the yield from the EtOAc-cyclohexane mixture was 200 mg (39%) of product, mp 167°-170°. For analysis the sample was dried in vacuo over Drierite for 1 hr. at the temperature of refluxing toluene: mp unchanged; uv λmax (pH 1) 334 nm ( ε 14 400); uv λmax (MeOH) 313 nm ( ε 15 800); uv λmax (pH 11) 316 nm ( ε 15 500).
