Procedure

Preparation of example 247 from Intermediate 147(d) of Example 147 (300 mg, 0.794 mmol) was carried out in three steps in a manner similar to that described for the preparation of Example 233 except that 1-prop-2-ynyl-pyrrolidine was used instead of dimethyl-prop-2-ynyl-amine in step 1. 1-Prop-2-ynyl-pyrrolidine was prepared by stirring 3-bromo-propyne, pyrrolidine and triethylamine at room temperature in tetrahydrofuran for 2 hours. The title compound (80 mg, 0.177 mmol) was obtained as a yellow powder in 36% overall yield.
