The 1-(6'-methoxycarbonyl-n-hex-2-enyl)-4-methyl-1,2,4-triazolidine-3,5-dione (12.4 g, 0.0486 mol) was dissolved in dimethoxyethane (200 ml) and 10% palladium on charcoal (3 g) was added and the resultant mixture was allowed to take up hydrogen (ca. 1100 mls). After the reaction was complete the resultant mixture was filtered through a kieselguhr bed and the filtrate evaporated in vacuo to afford 1-(6'-methoxycarbonyl-n-hexyl)-4-methyl-1,2,4-triazolidine-3,5-dione (12.3 g). m.p. 80°-1°.
