Procedure

PyBOP (86.9 mg) was added to a solution of tert-butyl (−)-[(4aR*,6S*,7aS*)-7a-(5-amino-2-fluorophenyl)-6-methoxy-4,4a,5,6,7,7a-hexahydrocyclopenta[d][1,3]thiazin-2-yl]carbamate (22 mg), the compound of Preparation Example 26-(2) (11.6 mg) and N,N-diisopropylethylamine (0.11 mL) in dichloromethane (2.2 mL). The mixture was stirred at room temperature for one hour. The reaction solution was poured into a saturated sodium bicarbonate solution, followed by extraction with ethyl acetate. The extract was washed with a saturated sodium chloride solution and dried over anhydrous magnesium sulfate. The drying agent was removed by filtration and the filtrate was concentrated under reduced pressure. The crude product was purified by silica gel column chromatography to obtain the title compound (29 mg).
