Abstract
A new process comprises <FORM:1040174/C2/1> <FORM:1040174/C2/2> <FORM:1040174/C2/3> <FORM:1040174/C2/4> <FORM:1040174/C2/5> <FORM:1040174/C2/6> combining a compound I with an alkali metal acetylenide II and hydrolysing the salt III to yield compound IV, which is then optionally hydrogenated to compound V which is finally dehydrated; in modifications of the complete process, (A) compound II is replaced by M-CC-CH2-NH-CHO and the formyl group is subsequently reduced to methyl; (B) compound II is replaced by M-CC-CH2OH and the hydroxy group is subsequently replaced by halogen and this replaced by a methylamino radical.
