rel-N-{[(3S,4R,6S)-6-(Cyclopropylmethyl)-3-(2,4-difluorophenyl)-4-(hydroxymethyl)tetrahydro-2H-pyran-3-yl]carbamothioyl}benzamide (C72) was converted to the product using the method described for synthesis of N-[(4aR,6R,8aS)-6-[(benzyloxy)methyl]-8a-(2,4-difluorophenyl)-4,4a,5,6,8,8a-hexahydropyrano[3,4-d][1,3]thiazin-2-yl]benzamide (C8) in Preparation P1. The product was obtained as a white solid. Yield: 430 mg, 0.97 mmol, 39%.
