1H NMR spectrum of the 9-chloride 2, two methine proton peaks are shifted downfield of the steroidal envelope to δ 2.2-2.4 and 2.5-2.7. In the spectrum of the steroid 9-bromide 4, two new peaks shifted downfield of the steroidal envelope, each of which had the same general line shape as those of the two methine proton peaks observed in the spectrum of the 9-chloride 2, were observed at δ 2.3-2.5 and 2.6-2.8.
