syntax in PUT request for HBASE

I keep getting an error for the following PUT request to an HBASE table.

curl -v -X PUT -H "Content-Type: application/json" --data '{"Row":
   [{"key":"aHR0cHM6Ly9tYWt6ZW9uLndvcmRwcmVzcy5jb20v", "Cell": 
   [{"column":"YmxvZ3NfZGF0YTp1cmw=", "$": 
     "aHR0cHM6Ly9tYWt6ZW9uLndvcmRwcmVzcy5jb20v"},
     {"column":"YmxvZ3NfZGF0YTppbnNlcnREYXRl", "$": "MTQ5Njg3ODk1OA=="},
   {"column":"YmxvZ3NfZGF0YTpzdGF0dXM=", "$": "QWN0aXZl"}], 
 }]}'    
http://1xx.xxx.xxx.xxx:8080/table2/https%3A%2F%2Fkeyurl.com%2F

ERROR:

HTTP/1.1 500 Unexpected character ('}' (code 125)): was expecting double-
quote to start field name  at [Source:

* Connection #0 to host 1xx.xxx.xxx.xxx left intact

I cannot find the problem. Also if someone could help convert that into a nodejs request, it would be very helpful.
