  "abstract": "We report the first observation of a number of decay modes of the B meson, namely $B^0 \\to D^{*-} (5\\pi)^+$, $B^+ \\to D^{*-} (4\\pi)^{++}$ and $B^+ \\to \\bar{D}^{*0} (5\\pi)^+$, where $(n\\pi)$ implies the combination of n charged pions. The analysis is based on a 140 fb$^{-1}$ data sample collected at the $\\Upsilon(4S)$ resonance with the Belle detector at KEKB. We measure ${\\cal{B}}(B^0 \\to D^{*-} (5\\pi)^+) = (4.72 \\pm 0.59 \\pm 0.71) \\times 10^{-3}$, ${\\cal{B}}(B^+ \\to D^{*-} (4\\pi)^{++} = (2.56 \\pm 0.26 \\pm 0.33) \\times 10^{-3}$ and ${\\cal{B}}(B^+ \\to \\bar{D}^{*0} (5\\pi)^+) = (5.67 \\pm 0.91 \\pm 0.85) \\times 10^{-3}$. We also provide improved measurements of the branching fractions for the decay modes $B^0 \\to D^{*-} (3\\pi)^+$, $B^+ \\to \\bar{D}^{*0} (3\\pi)^+$ and $B^0 \\to \\bar{D}^{*0} (4\\pi)^0$.",
