To a solution of 2.884 g (0.01 mol) of testosterone in 30 ml of dry benzene was added 1.008 g (0.012 mol) of sodium bicarbonate; then, while stirring, there were introduced dropwise 1.888 g (0.012 tool) of bromoacetyl chloride over a 5 minute period. The reaction mixture was then stirred under reflux for 6 hours until no testosterone could be traced by TLC. (Plates of Silica Gel G and a CHCH3 /CH3OH system were used.) The inorganic residue was filtered while hot, the filtrate was evaporated in vacuo and the residue was recrystallized from methanol, m.p. 144°-145° C., yield 3.2 g (78%). IR (KBr) 1735 (C=O), 1660 (C=O) cm-1. PMR as expected. The product has the formula: ##STR1506##
