  • Patent number: 4695635
    Abstract: 2-bromoergolines can be reduced in good yields, without dimerization as determined by NMR product analysis, to the corresponding 2,3-dihydroergolines under otherwise conventional reducing conditions by introducing 2-bromoergolines, together with sodium borohydride, into trifluoroacetic acid under cooling to prevent the reaction mixture from rising above ambient temperature.
