    • 6 in the co-axial inserts as an external reference (δ 29.800) and a lock-signal, and with readout of NMR spectra being adjusted to 0.001 ppm/point (sw=23980.8, fn=524288). The half-band width was 0.008 ppm. The chiral solvent 1 was recovered by Kugelrohr distillation (230-240°C/1 mmHg) after extraction with 1N HCl followed by basification and re-extraction of the resulting free amine with AcOEt
