DB:Raw not working for date format in postgres

I have the well executed postgres query.I have tried to convert this in laravel

but query not executed

select id,month,meeting_start_date,call_start_date from mgl_report_targets  
where extract(Month from to_date(mgl_report_targets.month, '%Month-%YYYY')) 
in (extract(MONTH from meeting_start_date), extract(MONTH from call_start_date));

 try 1         
 $db=DB::table('mgl_report_targets as t');
 $db=$db->where(function ($query){ 
 return $query->whereIn(DB::Raw("extract(MONTH from meeting_start_date)"),DB::Raw("extract(Month 
 from to_date('t.month', %Month-%YYYY))"))->orWhereIn(DB::Raw("extract(MONTH from 
 call_start_date)"),DB::Raw("extract(Month from to_date('t.month', %Month-%YYYY))"));
 })->select('id','month','meeting_start_date','call_start_date')->get();


but no luck.getting Parse error: syntax error, unexpected '}', expecting ';'

try 2
$db=DB::table('mgl_report_targets as t')
->where(DB::Raw("extract(Month from to_date(mgl_report_targets.month, '%Month-%YYYY')) 
in (extract(MONTH from meeting_start_date), extract(MONTH from call_start_date))"))
->select('id','month','meeting_start_date','call_start_date')->get();
 

nothing return from my try 2
