Gino's Suggestion and a Short Explanation
(1♦) - DBL - (Pass) - 2NT
(Pass) - 3NT - All pass
West prefers a takeout double over bidding clubs. Holding a poor 5-card minor suit, the club overcall should not be an attractive choice. West holds the correct strength (12+ HCP) and the correct shape (shortness in diamonds with 3-4 distribution in the major suits) for a takeout double.
Advancing the double, with a diamond stopper and no 4+ cards in a major suit, East should bid NT. With 12 HCP, East should make a game invitational bid, 2NT. 1NT would not be sufficient with this strength. Holding extras (14 HCP), West bids game.
