No baggage right? Otherwise MCT is 80 mins.[/QUOTE]

expertflyer shows 90 mins..not that MCT is relevant (technically), but even SQ-SQ is 60 mins for mist flights

Still, should be do-able if flights on time, no bags and the OP is quick off the plane and theees not much wait for the inter terminal bus (Long walk from the CX gates, just before immigration)- good luck to the OP!
