Dibromcotinine on hydrolysis yields oxalic acid, methylamine and 0-methyl pyridyl ketone: C10H10Br2N20+3H20+0= H2C204-ECH 3 NH 2 +C 5 H 4 N 000H 3 +2HBr; whilst dibromticonine yields methylamine, malonic acid and nicotinic acid: C10H8Br2N202+ 4H20=CH 3 NH 2 +CH 2 (CO 2 H) 2 +C 5 H 4 N CO 2 H+2HBr, or if heated with zinc and caustic potash, methylamine and pyridyl-ay-dioxybutyric acid.
