Gino's Suggestion and a Short Explanation
1♣ - (2♥) - 4♥ – (Pass)
6♣ - All pass
To simplify the auction, North should prefer showing a club fit over bidding diamonds. North holds a powerful hand (HCP and distribution). Just supporting is not sufficient to show strength. Responding a cue bid directly shows a fit and invitational+ values.
With a heart void and a slam invitational hand, North should prefer a jump cue bid, which shows a splinter! After the Splinter, South's decision to bid slam is straight forward holding extras in HCP and distribution.
