Procedure
By the reactions in the same manner as in Starting Material Synthesis Example 16 using 4-(methoxymethyloxy)-benzo(b)thiophene-2-carboxylic acid (3.0 g), pyrrolidine (0.75 g) and diethyl cyanophosphate (2.5 g), 1-(4-hydroxybenzo(b)-thiophene-2-carbonyl)pyrrolidine (2.4 g) was obtained as a brown oil. By the reactions in the same manner as in Starting Material Synthesis Example 1 using the brown oil (2.0 g) and (S)-glycidyl nosylate (2.0 g), the title compound (0.45 g) was obtained as brown crystals.
