    • note
    • Of critical importance to the success of subsequent coupling, excess oxalyl chloride was effectively removed by washing the dichloromethane solution with 0.5% sodium bicarbonate solution. This was accompanied by small amounts of methane[35]sulfonyl chloride hydrolysis (10-15%). The solution was then dried over sodium sulfate and concentrated by atmospheric distillation.

    • Enhanced hydrophilicity (water solubility) is usually inversely related to the observed "stickiness" of the radioligand which often severely restricts its usefulness in various receptor preparations, see: Bailey, G.
